Matlab编写BPSK信号通过AWGN信道的仿真过程-Matlab write BPSK AWGN channel signal through the simulation process

实现了pcm调制的全过程的MATLAB仿真，包括调制、A率压缩、量化、解扩、解调、信号恢复。 _pcm_coding_是另外一个单独的PCM编码程序-Pcm modulation realized MATLAB simulation of the entire process, including the modulation, A-rate reduction, quantization, despreading, demodulation, signal recovery. _
