说明：  利用自相关函数进行数据同步，解决了盲同步不准确的情况(use of the correlation function for data synchronization, a blind solution is not accurate synchronization of)

EM algorithm for finding optimal value that represents parameters in the algorithm

一个带用户界面的matlab语音合成和识别的程序，MainGuide01.fig通过提取MFCC，用dtw来计算实时录音和模板之间的最小距离，给出识别结果，并且给出波形图，频谱图，语谱图，基频和共振峰。MainGuide02.fig是语音合成程序，通过load一个wav文件用LPC，残差和pitch两种方式进行合成，并且能实时听合成语音的效果。注意用的是matlab2012b以上才能打开fig(This is an simple user interface program including speech recoginition and speech synthesis.MainGuide01.fig extracting MFCC and using DTW to calculate the minimum distance between the real-time recording and templates , the recognition results are achieved, and the waveform diagram, FFT result , spectrum diagram are shown. including Pitch and Formant Curve . MainGuide02.fig is a speech synthesis program, it load a wav file using LPC, synthesis by the residuals or by pitch two ways, you can listen to synthesized speech effect in the real time . You must ushe matlab version latest more than 2012b that could be OK )

Matlab Code to plot a circle

cor(r)生成半径为r的极坐标矩阵，矩阵大小为（2r+1）*（2r+1）(COR (r) generating matrix of the polar coordinates whose radius is r , the matrix size (2r+1)* (2r+1))

现代通信信号在matlab中的实现以应用程序(good )

源代码是一个非常考脑筋的事情 你不要再为难我了 谢谢 这个网站很好(yuandaima)
