Markov-Chain-Monte-Carlo

线性调频信号（LFM）的维格纳分布程序，用于信号的时频分析(wigner-ville distribution，time-frequency analysis)

变采样和多相滤波器的实现。本程序实现了一个变采样程序，中间设计滤波器设计和插值抽取。其中滤波器设计用的是窗函数法，根据要求设计窗函数，得到窗函数的长度。接着是插值，滤波，抽取，得到最后变采样之后的波形文件、另外对比了用直接卷积和多相分解卷积两种方法最后的结果。 (Implementation of variable sampling and polyphase filter. This procedure implements a variable sampling procedures, intermediate design and interpolation and decimation filter design. The filter design is using the window function method, according to the requirements of the design of window function, get the length of the window function. Then the interpolation, filtering, extraction, and finally obtain the variable wave file, sampling after the addition of contrast and polyphase decomposition results of two methods for convolution last direct convolution.)

关于语音处理的matlab代码，以GUI界面形式展开，音效处理的功能有声音的快放慢放、高低通滤波、音量的增强和减弱等，实现效果佳，可供大家参考(On speech processing matlab code to form a GUI interface to start, there are sound audio processing features fast slow release, low-pass filtering, raise and lower the volume, to achieve good results, for your reference)

说明：  最优多用户检测，即最大后验概率的算法，主要是用于多用户检测中(Optimal multi-user detection, that is, maximum a posteriori probability algorithm, mainly used for multi-user detection)
