用于均衡DPSK信号的JD-MLSE算法，为matlabb程序，输入DPSK解调的两路信号，判决得到所需的bit序列，并计算误码率-It s used for electronical equalization based on joint-decision maximum likelyhood estimation (i.e. JD-MLSE).

代码中含有信号处理算法中应用到的模糊度函数（单频信号、线性调频信号）及最大似然检测和估计算法，findpeak为峰值寻找算法，M kay为Steven M.Kay一书中描述的最大似然算法-Maximum code contains signal processing algorithm applied to the ambiguity function (single-frequency signal, the chirp signal) and maximum likelihood detec
