Applied Program: Wireless Telecommunications
On August 27, 2002, at the Central Institute of the Datang Telecom Technology and Industry Group based in Beijing, a young woman, full of energy and self-confidence, was giving a presentation entitled “The Design of the Switching Numerical Method of the Radio Resource Management (RRM) Strategy in TD-SCDMA, and the Testing of Its Simulated Systems,” which received rapt attention and high remarks from all the experts in Computer and Telecommunications who attended the meeting. That woman was I. At present, TD-SCDMA, W-CDMA, and CDMA 2000 are considered the main technological standards in the third generation of the world’s technological development in mobile telecommunications. And the design of a switching computation method for the RRM Strategy is a key element and technological crux for the TD-SCDMA technology. In retrospection, I found that it was my great enthusiasm for mobile telecommunications, and my persistent pursuit of accuracy and perfection that have helped me win accolades from colleagues and experts.
In China, since the TD-SCDMA uses a smart antenna, it makes a demand for a finer research on the computation method for the RRM Strategy, in areas such as PC, DCA, and HC. To me, a new starter in the company, it was a real challenge. Since the research team was new, it lacked engineering data and practical experience, although the equipment of the lab was quite advanced. It was only after much library research, thinking, and consultation with experts did I find a RRM computation method suitable for a smart antenna. Because a smart antenna has its advantages of a more accurate VE locating and reduced searching areas, this computation method effectively lowers the complexity of the switching process and its failure rate. During the time when I worked for the project, I often stayed up several days in a roll to perfect a lab test. But I also derived an enormous sense of satisfaction and fulfillment after overcoming obstacles, which more than compensated the pains and difficulties that I had to go through.
The rapid development of mobile telecommunication technology places a high demand on professionals working in this field. To a certain extent, it has to be a labor of love. My keen interest in mobile telecommunications emanated from the concept of “personal communication.” During my undergraduate years at the Northwest University of Industry, I spent much of my spare time browsing over professional publications and journals, to keep myself abreast of current developments. The concept of “personal communication” I encountered during this process impressed me immensely. A system of “personal communication” is one that allows the user to communicate at anytime, anyplace, to anyone, and in any way. It painted such a beautiful of picture of a future society that I became fully convinced that it is a subject well worth my lifelong pursuit. This was why I chose Mobile Telecommunications as my area of specialization in the graduate program. As a graduate student, I completed several research projects independently and successfully, including, for instance, “Turbo Code and the Application of Its Coding Concept.” In short frame conditions, the Turbo Code, with its improved application in engineering, seems to have a bright future in real-time voice-data service (Please see the attached article). After completing my graduate degree, I entered Datang Group, a pioneer in China’s software development. Here I did software design for the switch control template used at the RNC equipment for the TD-SCDMA system, and developed a switching computation method for the RRM Strategy. I went through the entire process of software design for the switch control template for the RNC equipment, from topic analysis to the project outline and then to actual program writing.
The present development of telecommunication technology indicates that the smart antenna, software radio, and the transmission technology of subline 下行 high-speed subdivided exchange data (下行高速分组交换数据传输技术) are key technologies for today’s mobile telecommunications. Software radio, in particular, has attracted much public attention. The use of DSP and software to solve the problem of wireless interfaces of diverse standards on a public hardware platform has become a major issue pursued by many professionals in our field. I too hope to make my own contribution to the technological development in this area. In the next few years, the traditional concept of using chips to build wireless equipment for mobile telecommunication will be seriously challenged. In recent years, the technologies and standards of the third generation of mobile telecommunication have been rapidly updated. Software radio, I believe, will be the future of our trade.
My desire to know more about computer engineering prompted me to rise above my present conditions. The United States, as technological superpower, have first-rate teaching faculty and research facilities in the world. Its ideological openness and tolerance make a sharp contrast to Chinese culture, which tends to value tradition rather than innovation. Wireless telecommunication may be said to be one of the newest research areas, and it is new concepts and new vision that give life to the industry. I believe that in the fine research environment in the United States, I will be able to make “shortcuts” in attaining my academic and career goals.
I would like to apply for admission to the Center for Wireless Telecommunications of Virginia Polytechnic Institute and State University. As the most prestigious research institute in Wireless Telecommunications, the Center has a large number of famed scholars and professionals dedicated to the theoretic research of Wireless Telecommunications. Meanwhile, it maintains close contact with the telecommunication industry, and in this way can test the theory in practical experimentation, which in turn promotes theoretic research. It is an ideal place for me to fully develop my research potential.
I look forward to finding a teaching position at college level in China after completing my graduate education, which will allow me to continue my research work in Wireless Telecommunications. I will impart my theoretic and practical knowledge to my students, and hope that this will benefit China’s wireless telecommunication industry, and society at large. I will make every effort to make the idea of “personal communication” a reality.

Personal Statement
"I have a lot of dreams."
"If we dream, everything will be possible."
In retrospect, I have much to be proud of. As a 10-year-old teenager, I was already obsessed of painting the concrete forms of my dreams with the brush in my hand. At such a young age, I had already learned the necessity to practice painting deep into the night in order to achieve constant improvement in the sophistication of my brushwork. My endowments and my dedication helped me secure three major prizes at international adolescent fine art competitions. My substantial progress in practicing fine art also opened the door to developing my perceptive horizon and to tapping my tremendous potential. As a result, I handled my studies with much facility, especially in mathematics for which I had a particular penchant. No matter how difficult the courses in my high school were, I could almost invariably achieve full marks in all of them. Apart from virtually perfect performance in the scholastic aptitudes at my school, I achieved remarkable scores in a variety of national contests for high school students in mathematics, physics, and chemistry. Those distinguished achievements resulted in my being enrolled by Tsinghua University, exempted from entrance examination. In China, this could properly be deemed the highest honor that a high school student could possible attain.
"On the way to the realization of your dreams, there is no substitute for hard work"
"Teamwork fulfill your dreams easily"
Upon entering this most prestigious university in China, which is Tsinghua University, in my usual spirit of dedication and perseverance, I once again embarked on my journey of industrious study in the Department of Automation. My exceptionally solid foundation in mathematics provided me with a stepping stone with which I proceeded onto the exploration of other sophisticated and erudite subjects. As a freshman, I taught myself such mathematics courses as Real Analysis and Advanced Numerical Analysis that are only scheduled for senior students. My performance in all the specialty-related coursework not only enabled me to secure the second highest GPA ranking in my class but also furnished me with a powerful instrument whereby to materialize my dreams in the research and development of computer and network technology.
In the scorching summer of 1999, with an entrepreneurial passion that was much more vehement than the scorching sun, two classmates and I commenced to establish our own business and to operate our own company. By any imagination, it was a challenging undertaking. We focused on the development of online multimedia entertainment platform and on the research and development of virtual reality (VC) technology. In the process of developing the software for the VC products, we encountered the major obstacle of how to realize globular equation of the pictures actually taken of the real objects.
Under my organization and leadership, the task team, which consisted of a number of senior undergraduates and graduates, consulted a huge amount of technical literature, solicited professional guidance from specialists in the field, conducted surveys and interviews, analyzed feedbacks, and wrote business proposals. It was common for me to sleep only four hours a day. We worked under the conviction that, even if we failed 99 times, we would be ultimately victorious if we could succeed in the 100th trial. Any notion of defeatism would cause one to relinquish and end up in eternal failure.
Within two months, we eventually succeeded in developing the semispheric equation algorithm whose effect could perfectly parallel the globular equation algorithm of the software. In autumn, the season of harvest, we won the Prize for Excellent Original Conceptualization at the annual Entrepreneurial Competition with the business proposal based on this project. In the meantime, we succeeded in attracting a risk, investment worth 5 million RMB (approximately 600000 US dollars). The immediate infusion of the cash into our company guaranteed the overall inauguration of our company.
In the initial stage of establishing our business, we foresaw that the VC technology would make tremendous headway in the future network application. The problem we faced at that time was the limited bandwidth of the network, which in turn circumscribed the development of VC technology. After nearly one-year development, our technology has become increasingly mature. Furthermore, our collaboration with Britain's Rotography Company has acquainted us with some refreshingly constructive concepts. With the continued improvement of the China's domestic network environment, we have formally initiated serial services to our clients in the application of VC technology. In this process, our company's website for supplying technical service www.senex.net was consummated. So far, many manufacturers availed themselves of our VC solutions, including Beijing Garment Manufacturing Factory, the largest of its kind in Beijing. Meanwhile, I participated in a seminar on the development of network virtual passage "VPN" project jointly undertaken by Zhejiang University and NingPo Golden Leave Information Technology Company. By conducting a survey of U.S. VPN market and by studying VPN technology, I presented some unique insights of my own at the seminar, which were positively evaluated by computer specialists from Zhejiang University.
With our products started to increase the market share, the reputation of our company became increasingly widespread. As a burgeoning company, we managed, through fierce bidding, to secure a project of Demonstration System from Sony Company. Though finally the project did not take long to complete, the success of winning the first project through tender excited the whole group of young entrepreneurs. At present, in reaction to the strong demands for information concerning rubber market by more than 20000 manufacturers and related enterprises, our company is cooperating with Reuter Agency and Information Headquarter of China National Rubber Industry in developing and designing "China Rubber Business Website", which aims at providing the most updated global rubber information for domestic rubber manufacturers and ultimately realizing the B2B business platform for China's rubber industry. This is a newly-emerging field which integrates conventional industry with IT industry, thus requiring rich professional knowledge and experience in conventional sector as well as powerful and comprehensive analytical and problem-solving capability. Under such circumstances, I am forced to augment my knowledge in a totally strange profession within the shortest possible time. But I know that with, my usual confidence, I will surmount this challenge.
"If we can dream it, we can do it."
"The future belongs to those who believe in the beauty of their dreams."
Now I have a dream to become a well-trained engineer so that I can enjoy myself in the field of technology application as well as in the field of theoretical research. Furthermore, I love the feeling of being challenged. Only by plunging oneself into a challenging environment will one be able to keep on scaling new heights. For me, this challenging environment that fascinates me most is Harvard University, the ideal university to undertake my Ph.D. program.
In my prospective degree program, I would like to concentrate on the following fields: (a) VLSI & Microelectronics; (b) Systems and Control; (c) Robotics and Computer Vision; (d) Communications & Signal Processing; (e) Operations Research & Systems.
I am convinced that the advanced training in your established graduate program will help develop me into a successful professional in my chosen field. In the highly challenging academic environment of Harvard, I will rely on two effective strategies that I have consistently employed in my heretofore studies and business operations: competition and cooperation. I can imagine that, with the international perspective and professional expertise developed at Harvard University, I will be best assisted in bringing my tremendous potential into full play in my future efforts to blaze new trails in the virtually unlimited future world.

Program: Teenager & Juvenile Developmental Psychology
In my undergraduate program, I received education across two fields—a degree program in law at the Law School of XX University and a degree program in psychology at XX University. My rigorous academic trainings across those two fields have given me necessary qualifications for pursuing a more advanced program either in psychology or in law, endowing me with a unique advantage in interdisciplinary knowledge.
As far as I am concerned, law and psychology are reciprocal. They all pertain to human behavior. As a matter of fact, my thesis in law, entitled “ XXX “ explores juvenile delinquency by examining the complicated psychological factors of the younger generation of China in family, school and neighborhood settings. However, there are essential differences between them. In terms of the causal relationships of human behavior, law is primarily concerned with the treatment of the consequences of human behavior while psychology probes into the motivations that cause people to act as they do. In the framework of human relations, law aims at orderly and well-regulated social relationship while psychology, with its interventions into the process of human development, seeks to facilitate the healthy development of the individuals.
While law and psychology are both indispensable to the proper functioning of our society, when it comes to making a choice between those two fields in which to pursue a graduate program, I decide to opt for a program in Developmental Psychology. My decision is motivated by the fact that law can only deal with the aftermath of human behavior whereas psychology can provide preventive measures against possible negative human behavior. Child & adolescent psychology, a field I am interested in, may facilitate the development of healthy personality structure that may enable children and adolescents interact with the society in a harmonious manner.
I have received sound academic trainings that a student of psychology can expect in China, excelling particularly in Developmental Psychology, Cognitive Psychology, Experimental Psychology and other core courses, all of which have imparted to me the necessary theoretical knowledge. My 87/100 GPA in Psychology has made me the top student in my class and the winner of a series of the university’s top-level scholarships. As an undergraduate, I have attempted at some tentative research by submitting essays and research papers to provincial-level and university-level journals (please refer to my Resume). In performing those researches, I find that I have benefited considerably from my solid mathematics foundation and the related methodology—my score for the Advanced Mathematics course is 98/100 while the SPSS was nearly full mark. I have mastered important statistical and quantitative methods, computer programming and LISREL with much facility and I excel in designing experiments and preparing questionnaires.
I started to perform formal academic research at the Developmental Psychology Lab in XX University two years by working as a research assistant to Prof. XX, a leading Chinese scholar on social development in childhood and adolescence and peer relations. By focusing on the peer relations, social cognition, social self-concept, attributions, and past social experiences, I completed a full-length research paper XX, which became a poster presentation at the XX. My research indicates that in addition to maintaining an appropriate level of social self-concept and optimistic attributional style, it is essentially worthwhile to emphasize another two strategies to improve the positive peer nominations: to pay special attention to the attributions to negative events of the life, and to attribute social popularity or success to some stable causes. Based on my distinguished academic performance, I attended the XX and the XX.
Off campus, I have worked as a social worker offering psychological consulting for the “No Worry Teenagers” column for the authoritative journal XX, dealing with the problems concerning interpersonal relations and social cognition of adolescents and young adults. This experience allowed me to gain insight into many important aspects of the mental lives of this group of people beyond the mere statistical data. However, it is a regret that my knowledge is insufficient to offer adequate consulting service to my audience of such diverse backgrounds. This fact reveals to me the need to undertake more advanced studies to improve my professional competence.
I am strongly interested in the developmental psychology of adolescents because by helping adolescents build up a healthy psychology that may enable them to successfully integrate into the competitive world of adults, hence fewer social problems could be created. In my proposed program, I would like to concentrate on the following subjects: social cognitive and social-emotional development in childhood and adolescence; peer relations and family relations and their influence on development; resilience in high risk settings; development of self-esteem; gender differences and similarities, and research methods. The University of XX’s graduate education is very strong in those fields. Your faculty consists of distinguished professors who come from leading universities and have made important research achievements. Your program offers students a total of 14 labs, among which Multiple Identities and Interpersonal Interactions Lab is most relevant to my study. I expect that your Ph.D. program can give me instruction in the fundamental theories and knowledge of developmental psychology and also give me rigorous training in planning, conducting and evaluating research. I would like to identify Prof.XX as my potential advisor, whose research interests covers a wide spectrum, including most of the fields I am interested in.
To me, psychology means care, psychological research is to find out how to care and psychological service is to offer the care. My career objective is to develop into a research-oriented professor who can perform substantial research on adolescent psychology. I will study those features of psychology that Chinese adolescents share with their XX counterparts as China is under heavy influences of XX culture. But I would also examine the role of traditional Chinese culture in shaping the psychology of Chinese adolescents. Apart from my professional activities, I will continue to offer voluntary, non-profit consulting services to those who are in need. Adolescent psychological consulting is only of recent origin and much is to be improved. My prospective XX education will enable me to make important contributions in this regard.
