少说诸如“ hiermit bewerbe ich mich...”这样的废话。比较好的做法是列举最重要的论据德国留学生动机信写作要求一览表，以支持自己所说的内容。例如：“我在企业管理学专业(BWL)以优异的成绩毕业，学士论文也是和电子市场相关，这些使得我想要申请网络营销专业硕士，以作为目前所学专业的自然延续。”
Dear Sir or Madam,
I would like to apply for the English-Taught Master degree in Communication Engineering, which starts in December 2011. I am a BSc(Eng) in Telecommunications Engineering with Management, which is a joint degree program between Beijing University of Posts & Telecommunications(BUPT) and University of London.
Reasons for choosing CE of RWTH Aachen
I had spent nearly two years seeking the way of my life from 2007 till 2009.
Initially, as a freshman, I concentrated on the work of Student union and Beijing IETYME (Institution of Engineering and Technology Yong Member Section). As a result of my hard work, I was elected vice president in the third semester. However, instead of feeling much pleasure and excitement, I could not work up too much enthusiasm for the iterative activities.
Then I understood that the work of organization management didn’t really fit me. Naturally, I transferred my focus to study. I was heartily satisfied when I overcame puzzles even though the two-year distraction brought me great difficulties at the beginning. Since then, I started to realize that this should be the way of my life. I also found that I am most attracted by subject concerns with communication systems and excelled in courses such as Introduction to the Communication, Telecommunication Systems, Signals and Systems Theory, Internet Protocols, Digital Signal Processing and Microwave & Optical Transmission.
Through these courses, I learnt the simple infrastructure of communication system and basic theories such as Sampling, Quantization, Channel Coding, Queuing Theory, Fourier Transforms, Wireless Network, Digital Filter Design and Routing Protocol. However, I was still confused with questions like what parameters would influence the practical operation of equipment, how to integrate the single units, how can I make improvement to avoid disadvantages of existing theories.
In the summer of 2010, I participated in school laboratory which took charge of MIMO System optimization, one of national key scientific research projects. I keenly felt the lack of knowledge over that period, and was figuring how to exactly calculate the channel capacity in different conditions, how to instantly transfer channel state information (CSI) to transmitter antennas, how to apply the ideal model in the complex realities. I found these questions very fascinating.
Obviously, it is impossible to solve those questions with the current knowledge I leant in my undergraduate period, thus I decided to further my study. Another important reason is that what we learnt lags far behind reality, which can’t support me in operating advanced equipment. For example, the 8051 microcontroller I learnt in the course of ‘Microprocessor System Design’ was applied in 1990s.
While doing microwave experiment, my teacher mentioned that among the top three companies: Anritsu, ROHDE&SCHWARZ and Agilent, which produce VNA, R&S owns the unparalleled predominance compared with the other two companies.
Germany owns the most advanced technologies, the best research groups, first-rate industrial technology and rigorous elite education system, which strengthen my wish to continue my studies in Germany. RWTH Aachen University, which is among the best in Germany, enjoys an excellent international reputation and brings together many distinguished scholars.
