用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。(Simulink tools used to write code (S-Function mode), resulting in a single Path Rayleigh channel, the Doppler spectrum for the classical spectrum, including mobile rate of 120km/h.)

Finite Element solution of Poisson equation

Wound-field synchronous motors are well-known in industrial drives requiring constant speed irrespective of load. Separately controllable dc excitation in the form of dc field current is a unique feature in the power factor control of such a motor the lagging to leading mode.

OFDM(含部分MIMO)综述性文章，希望能给刚接触这一技术的人一些帮助，已经熟悉这方面基础知识的人就不用下了(OFDM (with some MIMO) summarized article, I hope this technology can give people刚接触some assistance in this area are already familiar with the basic knowledge of us would not have a)

说明：  此程序为语音信号的过零率检测，白噪声过零率远远高于语音信号，故可通过对过零率的检测判断出是不是语音信号。(This procedure for the zero rate of speech signal detection, white noise zero crossing rate is much higher than the speech signal, it can zero rate by detection of voice signal is not judged.)

介绍粒子群算法的一种改进算法的实现代码，具有很大的参考意义。(Introduce particle swarm algorithm is an improved algorithm implemented code, is of great referential significance. )

利用MATLAB编制的绘图程序，对利用自己开发绘图界面很有启发(using MATLAB based mapping procedures, the development of the use of their graphics interface is very enlightening)
