实现直接序列扩频通信系统的仿真 其中有m序列的生成函数以及BPSK的调制解调(Realize the direct sequence spread spectrum communication system simulation Among them are m series generating function of BPSK modulation and demodulation)

GA(PSO)为GA和PSO单独优化算法，里面分了两个文件 一个PSO粒子群算法 一个GA遗传算法(GA (PSO) for GA and PSO optimization algorithm alone, which divided the two documents a PSO PSO algorithm a genetic algorithm GA)

Mutual Information Feature Selection

协作通信的方阵代码，适用于认知无线电协作频谱检测等(Phalanx code cooperative communications for cooperative spectrum sensing cognitive radio , etc. )

均匀圆阵部分阵元失效情况下的DOA估计方法(Part of uniform circular array element failure in case of DOA Estimation)

这是一个APF仿真模型，谐波检测采用ipiq方法，电流跟踪控制采用滞环控制，直流侧电压为PI控制(This is an APF simulation model, harmonic detection using ipiq method, the current tracking control using hysteresis control, DC side voltage for the PI control)

说明：  删除卷积码的matlab仿真,广泛应用于通信系统中(delete the Matlab simulation, widely used in communication systems)

算术编码的应用实例matlab版本 1.可以对字符进行算术编码 2.开头不必制定字符串的大小 3.编码精度高，达到小数点8位以上 4.以函数的形式给出，易于调用和移值实现 5.显示界面人机交互较出色 (arithmetic coding examples of the application of a version of Matlab. Be right characters arithmetic coding 2. Not the beginning develop the size of strings 3. Coding accuracy, reaching more than eight decimal point four. to function in the form given, easy to call and shifts to achieve 5. HCI interface shows more successful)

This is my first file, Graphical numerical solution

说明：  ldpc相关，涉及ldpc编码、和积译码(LDPC related, involving LDPC coding and sum product decoding)
