matlab 常用数学函数代码的说明与下载，对matlab的入门十分有帮助！pdf版本的！(matlab common mathematical description of the function code and download the entry of matlab very helpful! pdf version!)

说明：  DTMF的PDF说明文件，从原理到应用方法进行了详尽的叙述，使人理解双音多频的概念和使用方法(DTMF PDF Document from the application of the principle carried out a detailed narrative that people understand DTMF the concept and use)

comparison of Rayleigh fading channel with and without correlation

在相控阵基础上，每个阵元增加一个小的频偏形成的频率分集阵列方向图(the pattern of frequency diverse array)

计算时变的Hurst指数,包括主程序与子程序(Calculation time varying Hurst index, including the main program and subroutine)

用于语音识别即ＤＴＷ算法，计算两个语音信号之间的距离(DTW algorithm for speech recognition is to calculate the distance between the two speech signals)

永磁同步电动机的空间矢量控制simulink源代码(Permanent magnet synchronous motor with space vector control simulink source code)

说明：  本程序实现了短数据序列不同窗函数的welch功率谱估计，然后又求了他们的平均标准差，从而判断各个窗函数的优劣。只要稍作修改就能实现不同信噪比下的功率估计，同时也可以实现长数据序列的估计。(This procedure has a short data series of different welch window function power spectrum estimation, and then seek their average standard deviation, and thus to determine the merits and demerits of each window function. As long as we can with some slight modifications under different signal to noise ratio power estimate, but also the realization of a long data sequence can be estimated.)
