这个是用MATLAB中的SIMULINK做成的PCM编码器。(This is the MATLAB SIMULINK caused by the PCM encoder.)

Most of the string-functions are rather heavily hand-optimized, see especially strsep,strstr,str[c]spn.

混合扩频DS/FH仿真程序，从原始信号通过伪随机码，跳频码转变为混合扩频信号，再依次解跳解扩，最后通过低通滤波器恢复出信号。(Hybrid spread spectrum DS/FH simulation program, from the original signal by pseudo random code, frequency hopping code into a hybrid spread spectrum signal, and then hopping despreading, finally through a low-pass filter to recover the signal.)

本程序先生成一个“Blocks”信号，然后加上高斯白噪声，再用 db3 小波进行分解，(This procedure Mr. Cheng a " Blocks" signal, and then adding white Gaussian noise, and then ' db3' wavelet decomposition,)

维纳滤波的一个应用 是关于AR(4)模型的(An application of Wiener filtering is on the AR (4) model)
