本来想做一个BPSK的调制和解调的混合编程实验，由于混合编程的库里面没有butter、cheby1等滤波器函数，用C编又不会，所以只好请教高手了。呵呵~-Originally wanted to do a BPSK modulation and demodulation of the mixed-programming experiment, as a result of mixed programming library There are no butter, cheby1 function

利用matlab编程，编写了一个m序列的本原多项式，并且可以利用库函数求序列的自相关-Using matlab programming, wrote a primitive polynomial m sequence, and can take advantage of the library function uation autocorrelation

语音编码，混合激励线性预测，波形音频文件格式，低级音频函数，套接字，网络编程-very useful code
