已知一个信道的信噪比，求出相应的误码率，matlab实现，很好用，很多场合需要计算这个。反过来也是可以的。-Known signal-to-noise ratio of a channel, the error rate is obtained, matlab realize, well used, need to calculate the number of occasions. The reverse is also possible.

GMSK文件里面是一些关于GMSK和直接序列扩频综合实现的论文，包含MATLAB和Verilog实现方法。 GMSK_matlab文件里是GMSK调制和1bit差分解调的MATLAB实现程序。里面有信噪比为-10~12dB时，运行好的误码率数据mat文件，可直接出图。-GMSK file includes the paper about GMSK modulation and demodulation. GMSK_matlab file includes the matlab code
