误码率仿真讲义，在matlab环境中如何进行接收数据的误码率计算()

log5pitch : 将Hz为单位的基频转换为五度标记法规定的声调，先传入四个声调的基频，然后输出四个声调的五度值 myExcelWrite : 用matlab向Excel表单中写入内容(log5pitch: the fundamental frequency in Hz is converted to five times the tone mark law, passed in the first four tones of the fundamental frequency, then the output value of four tones of the five degrees myExcelWrite: using matlab to write content to an Excel spreadsheet)

清音和浊音的平均幅度，短时过零率，基音周期，对数幅度谱，高低时部分(Voiceless and voiced the average range, short-term zero crossing rate, pitch period, the number of amplitude spectrum, high or low section)

好用的互信息程序，可以计算时序信号的互信息以及熵等。可以直接使用(it is used for multil-information,and it can be used directly.)

说明：  MATLAB多目标搜索算法工具包，包含了各种测试函数(MOEA toolbox for MATLAB)
