说明：  里面有8PSK，GMSK的matlab源程序，贡献出来了(I was interested in the theory for 8PSK and came across this m-file written in 1999. It requires 2 function calls (graymapPSK and grayunmapPSK) which I have included and must be uncommented(single comments only) and loaded into your workspace. Remove the function calls from this m-file after you load into your workspace. It seems to work well and give valid results for BPSK and QPSK but I have a question about the setup for 8PSK and the solution for Pseint where Pse=Pseint. Also, the Gray coding seems different than what I m used to. Some of you more theoretical minded may have some insight into the theory behind how Pseint was determined and comment. I don t have the communications toolbox-blockset and was wondering how it compared with Matlab s example simulation of 8PSK with Gray coding (in Simulink?) Each run takes about a minute and the loop iterations are shown in the command window. A numerical example of a satellite link is shown using uncoded QPSK )

介绍了坐标变换在异步电机中的应用条件和原则，以便能够快速地在异步电机中选择合适的坐标，提高工作效率．并结合异步电机矢量控制存MT坐标系中变换后，可类似于直流电机的转矩电流分量和磁场电流分量(the vector control of asynchronous motor based on the right coordinate)

基于MATLAB的times_two详解，主要解决的是times_two的问题(Based on MATLAB-times_two explain, the main problem lies in the question of times_two)

POCS算法实现，较为全面，使用的一个程序。 (POCS algorithm)

说明：  使用matlab的霍夫曼编码简单实例，输入包括给定概率表和字符串输入，输出包括编码后的结果和，解码后结果(Huffman encoding matlab use a simple example, the input comprising a given probability table and string input, output, including the results of encoded and decoded Results)

巴特沃斯滤波器，主要实现的是低通信号，此功能模块的低通曲线很符合理想的幅频特性。(Butterworth filter, the main achievement is low traffic numbers, the low-pass curve is consistent with this function module ideal frequency characteristics.)

聚类，就是单纯的聚类算法，别的我也不知道啊(I CAN NOT SPERK ENGLISH)
