用MATLAB编写的语音信号的短时分析，主要包括：分帧、短时能量、短时平均幅度、短时过零率、 wPqmRn函数、短时幅度差、倒谱、复倒谱 bAflVNH系数计等，是我多年调试通过的程序 (MATLAB prepared with short-term analysis of the speech signal, including: framing, short-time energy, short-term average amplitude, short-term zero rate,wPqmRn function, short-term amplitude difference, cepstrum, cepstral bAflVNH coefficient meter, etc. , is a program debugging through my years of )

读取语音信号（用matlab的wavread指令），把语音信号分帧、加窗，进行清浊分割，提取基 频，这一部分较简单，自己编程序做。参考文献自己到图书馆期刊网上查找。 提取语音信号的lpc参数，可调用lpcfit.m 程序（我提供，见附件），将源、目标语音的浊音 段的lpc系数进行DTW规整，调用pathita2.m 程序（我提供，见附件）。将规整得到的lpc系数 转换成lsp参数，调用lpcar2ls.m 程序（我提供，见附件）， 再进行转换映射，调用matlab 的指令newrbe。(read the speech signal (using Matlab wavread Directive), Voice Signal frames, Windowed, Qingzhuo segmentation, extracting fundamental frequency, this part is relatively simple, they programmed to do. References their online journals to the library search. Voice Signal Extraction lpc parameters can be called lpcfit.m (I provide, see Annex), the source, Voiced objective voice of the lpc coefficient DTW structured, Call pathita2.m (I provide, see Annex). Structured to the lpc lsp conversion coefficient parameters, calling lpcar2ls.m (I offer see Annex), the shift mapping, called the directive newrbe Matlab.)

说明：  此函数是初学结构光的学生使用的，本人写的光栅生成代码，直接可以运行(This function is used by beginners of structured light. The grating generation code written by myself can be run directly)

Max Log MAP decoding

SRM angle plotting model

matlab程序：将输入的字符按照ASCII码排序后输出(matlab program: the input characters are sorted according to the ASCII code output)

说明：  对信道的仿真，采用QPSK调制，分别在瑞利和高斯信道条件下，也包括CRC较验(Simulation of the channel, using QPSK modulation, respectively, Rayleigh and AWGN channel conditions, but also more experience CRC)

通信信号数字调制识别源程序，包含六种常见的调制方式(Digital modulation recognition of communication signal source, contains six kinds of common modulation)

ofdm系统仿真 含16qam调制 fft 加窗 加cp等模块，计算互信息非常有用的一组程序,通过反复训练模板能有较高的识别率。( ofdm system simulation including 16qam modulation fft windowing modules plus cp, Mutual information is useful to calculate a set of procedures, Through repeated training MWHEWaHlate have higher recognition rate.)
