基于matlab的自相关提取基频算法（结合了带通滤波，三电平削波）(Autocorrelation matlab-based fundamental frequency extraction algorithm (a combination of band-pass filter, three-level clipping))

information.m用来计算两个一维向量x和y的互信息。把压缩包中两个程序放在一起就可以运行(information.m used to calculate the two one-dimensional vectors x and y of the mutual information. The compressed package of two programs can run together)

M和m序列发生器，用于扩频通信中产生长度为2^N和2^N-1的伪随机码。同时还有产生bpsk调制的扩频调制和解调系统仿真，以及gold码的mat文件。(M and m sequence generator.Used for spread spectrum communication to generate the spread code.As well as bpsk spread spectrum system communication simulation.)

改进的子块重叠局部直方图增强算法。但达不到实时处理的速度。希望能和同仁交流(Improving LHE. But fail to real-time processing speed. And hope to communicate)

在matlab上实现2ASK信号的调制，以及相干解调，并给出调制/解调后的信号波形。主程序名为ASKmod.m，调用子程序为T2F.m、F2T.m、 和LPF.m。(To achieve in matlab 2ASK signal modulation, and coherent demodulation, and given modulation/demodulation of signal waveform. Main program, called ASKmod.m, call subroutine to T2F.m, F2T.m, and LPF.m.)
