From the very outset of my undergraduate program at the Department of Electrical Engineering of Tsinghua University, most prestigious for its engineering education and for its galaxy of engineering talents in the entire nation, I have been wondering how I can be an elite of elites. Now, as I come to the final stage of my program, I am convinced that I have found its answer – a distinguished academic performance, an abundance of research experience, and a broad exposure to the latest developments in the academia, and the determination to pursue continued excellence, all of which I have succeeded in developing.

Studying in a highly competitive academic environment is often described as “sailing against the current; the failure to advance means falling behind.” This is especially true at Tsinghua University. However, as the infallible winner of gold and silver medals in dozens of physics, chemistry and mathematics competitions during middle & high schools, as a member of the Team of Olympics Mathematics of Beijing Municipality and then of China National Team, and matriculated into Tsinghua University as the top 7 among 180,000 Beijing participants in the highly selective national college entrance examination, I was well equipped to sail “against the current” and to forge ahead.

I have maintained rounded development throughout my undergraduate program. Academically, I have achieved an overall GPA of 88.789 on a 100-point grading scale, ranking top 3 in my class and top 11 in the entire grade. My academic excellence is further testified by the fact that, even though the difficulty of coursework increases year by year, my ranking has demonstrated an ascending momentum. My mathematics aptitudes have grown much more advanced. I achieved 98 and 99 for Calculus (1) (2) and Geometry and Algebra (1) (2) respectively in the freshman year and full marks for 4 compulsory courses in the sophomore year. My score for the 3 projects in the course Stochastic Processes was among the top 3 in the entire grade.

In terms of my performance in my specialty, I have excelled in almost all the courses, particularly Analogical Electronics, Logic Design and Digital Systems, Signals and Systems, Communication Circuits, Principles of Circuitry, Principles of Modern Communication, Computer Network. With highest scores in some of them, those courses are highly relevant to the program that I am applying for. While doing my coursework, I participated in our department’s annual electronic devices contest that allowed me to apply knowledge to practice. In two of those contests, I designed and produced Wireless Remote-Controlled Ball-Hitting Electronic Vehicle which, through a department-wide presentation and defense, allowed me to savor the joy of creativity.

Learning through failures is sometimes more effective than through successes. In doing experiments on Analogical Electronics, I undertook a design project on Distance Detection Through Ultrasonic Waves. PSPICE and EWB simulation software all indicated my circuit design “perfect.” However, when the “perfect” design was realized on the circuit board, the wave pattern proved rather unstable and the voltage of some components did not agree with simulation statistics. This experience taught me that software simulation, based on idealized states and approximations, is not totally trustworthy and every design detail must be subjected to the most rigorous scrutiny.

What has made me most proud of my research potential is my creative idea in digital image processing, which marks my increasing academic maturity. Having read in a technical journal about solving seamless cloning by applying the approach used to work out the discrete possion equation on image processing, I decided to undertake a simulation on this interest project, even though the simulation required a large-scale linear equation system. The paper in the journal proposed two ways of realizing the equation system-- Gauss-Seidel iteration and V-cycle Multigrid. Although those two algorithms’ temporal complexity was not great, their spatial complexity was considerable. As the internal memory of my computer could not support large-scale matrix operations, I tried designing a locally optimized iteration algorithm with which to scan each pixel in the image to achieve optimum local results. As each optimum value obtained showed decreased overall errors and minimum value, after a certain number of iterations, I could always reduce the variations between any two iterations to a tolerable margin and obtain an approximation. My approach, although somehow increasing temporal complexity, significantly minimized spatial complexity and ensured my ultimate testing of the algorithm. My advisor expressed his ready appreciation for my conceptualization and methodology.

Studying at Tsinghua University, one of the most influential Asian universities in communications, afforded me many special advantages. In addition to receiving important interdisciplinary input, I have studied classic textbooks like Signals and Systems by A. V. Oppenheim, attending lectures and workshops hosted by the world’s leading scholars such as Progress on IEEE 802.16 WG by Dr. Roger B. Marks, chair of 802.16 WG, Information Theory, Queuing, and Resource Allocation in Wireless Networks by Prof. Edmund Yeh from Yale University, IEICE distinguished lecture Towards the Beyond-3G Wireless Network—Ad Hoc Networks and Space-Time Transmission Techniques by Prof. Susumu Yoshida, undergoing CDMA training program launched by Mr. Richard Dean, vice president of engineering technology of Qualcomm Ltd. on CDMA 2000 Network Planning and CDMA 2000 Speech Network Optimization, and participating in the Conference on the B3G Technological Cooperation of Erickson Wireless Communication Research Center. Through those activities, I have been kept informed of the most sophisticated communication technologies in the world and my vision has been projected onto the new generations of mobile communication systems around 2010.

Perhaps a series of honors and awards I have received over the past three years can also indicate my multi-faceted excellence. I won the second prize in the First Departmental Hardware Design Contest (05/2004), the first prize in the Departmental Innovation Contest by designing (in collaboration with two classmates) the “Agelong” Wireless Long-distance Image Transmission of Micro Camera Shooting Probe (consisting of movement tracking system and movement detecting system, 03/2004), second prize in the 9th Structural Design of Tsinghua University (10/2002), SRT (Student Research Training) Best Performance Award (03/2004), Award for the National Mathematical Modeling Competition (09/2003, a project on SARS spreading and on how to predict suspected cases, confirmed cases and epidemic development), Star of Circuit Design conferred by Shanghai Xinzhi Electronics Co., LTD (02/2004), Second-class University Scholarship and First-class Department Scholarship (twice for each), and Kodak-Tsinghua Scholarship for Academic Excellence (09/2003).

By far, my greatest achievements lie in a number of internships and laboratory experiences in which I have developed the ability to acquire useful new knowledge and discover appropriate solutions in the shortest possible time. When doing internship this summer at Fujian Fujitsu Communications Software Co., Ltd as a team leader, I joined the company’s Research and Development Group working on the SMS of the PHS. By acquainting myself with the technologies of the project, especially the UT Starcom terminals, and applying my knowledge and practical skills in communication, I played an important role in helping the group successfully compile the AAA (Authentication /Authorization /Accounting) modules in the FS-PHSMS System. I further proposed to the company’s management the initiation of the “Long-Distance Wireless Data Connection Service” that could exploit the advantages of PHS and WLAN. Earlier this year, I interned at Shanghai Xinzhi Electronics Co., LTD where I compiled the 10-05 Work Procedure Database Software and carried out network optimization and software debugging for mobile communication system. Other internship experiences include working as assistant engineer at China Samsung Telecom R & D Center and as research assistant at SYNNEX R & D Center of Xiamen University (developing two subsystems Course Management & Student Management for the Information Management System). My most important experience has been working since Sept. 2003 as research assistant at two laboratories based in our university— State Key Lab on Microwave & Digital Communications and Radio Transmission & Personal Communications Laboratory — where I am engaged in 4G hardware platform design and testing.

Compared with average students, I have distinguished myself by the sheer energy devoted to my academic work and practices. Active and full of initiative, I am committed to becoming a high achiever in EE. I have been comprehensively exposed to all the major fields of EE and have laid an unusually solid groundwork for more challenging academic pursuits. In my proposed Ph.D. program, I plan to focus on optical communication system, optical wireless communication, wireless multimedia transmission, broadband communication, virtual wireless mobile communication system and network, with concentrations on Biomedical Ultrasound and Biomedical Engineering, Signal and Image Processing and Communications, and Integrated Electronics and Computer Engineering. The research experiences I currently develop from undertaking my Bachelor’s thesis Image Detection System in Wireless Network Environment will be my another important asset when undertaking your program.

In matching my academic, research and internship backgrounds with an appropriate institution in the United States, I find UC Berkeley to be my top priority. I have great respect and admiration for EECS faculty who are dedicated to research and discovery at the highest level, informed teaching, and the creative desire to excel. EECS faculty represent a broad range of top-flight people from all over the world and the United States, with many different backgrounds, thus making study at Berkeley truly exciting. Your 9 research areas encompass many of my own research interests—Communications; Control, Robotics, & Biosystems; Integrated Circuits; Networks; Optoelectronics and Electromagnetics; and Signal Processing. Through further research, I would like to identify Prof. x x x, Prof. x x x or Prof. x x x as my potential advisor because my interests bear most closely on any of them.

As an undergraduate with rounded development, I am determined to seek a first-rate education in the United States that would bring out all my intellectual potential. I am highly motivated and deem myself fully equipped with the necessary qualities for fruitful research—a fine academic foundation, basic research capacity, abundant practical skills, and the readiness to contribute either through leadership or teamwork. Above all, I will pursue scientific inquiries with an indefatigable spirit and rigorous methodologies. Since I have proved myself an elite student in the past, I have every reason to believe that I can develop myself into an elite researcher in the future.
