此程序是bpsk调制的程序，经过仿真正确，请放心使用，肯定没问题。-this procedure is bpsk modulation procedures are followed, simulation is correct, please rest assured that the use, certainly not a problem.

G.711使用64Kbps的带宽，可将14bits转换成8bits。目前G.711有两个编码方式，A-law以及Mu-law。-G.711 defines two main compression algorithms, the µ -law algorithm (used in North America & Japan) and A-law algorithm (used in Europe and the rest of the world). Both are logarith
