说明：  自己学习的，总结的，不是很好，大部分是书上的，最起码还游泳吧(Their own learning, lessons, not very good, mostly books, at least also swimming)

bpsk的各种代码，有高斯白噪声下的(BPSK various codes, have under the Gaussian white noise)

期望最大化算法的ppt，很不错，个人用了，很受益啊。。。(EM algorithm)

压缩感知重构算法在“鬼”成像中的应用研究.pdf(Compressed sensing reconstruction algorithm in the "ghost" image of applied research. Pdf)

wavelet,很好用的原码哦，一起试试吧(wavelet, with the original code Oh well, try it with)

给一个受污染的声音文件用滤波器用matlab消除噪声(Give a contaminated audio files using filter to remove noise)

2ASK(1)通信系统仿真进行2ASK调制，其中基带信号为单极性NRZ矩形波，采用相干解调方法对带通滤波器的输出信号进行解调；(2ASK (1) 2ASK modulation for communication systems simulation, in which the baseband signal is unipolar NRZ square wave, coherent demodulation method using band-pass filter output signal demodulation )

信号用m序列进行扩频，成型滤波和BPSK调制后经过信道发送到接收端，接收端进行解扩解调(Using m sequence spread spectrum signal, after forming filter and BPSK modulation channel is sent to the receiver, the receiver to enlarge demodulation )

说明：  A*算法可视化运行，支持随机地图，展示open和close表(Visual operation of a * algorithm, supports random map, displays open and close tables)
