《matlab编程百例》光盘代码36-39("Matlab programming hundred cases" CD-ROM code 36-39)

kpib.m contains code for GPIB and serial port communication for a number of scientific instruments, organized so that a single common command syntax can operate them all. For example, the command: r = kpib(INSTRUMENT,GPIB, read ) will return the voltage and current reading from a number of different power supplies. The goal is to be able to write matlab code that can accommodate changing instruments and experimental setups with minimum hassle. If INSTRUMENT and GPIB are defined as constants at the beginning of your code, then they can be changed to accommodate new equipment, and the rest of the code is unchanged. In addition, kpib can test whether an instrument exists at an address and read and write arbitrary strings to instruments for testing.

说明：  常规AM调制：画出调制前波形图和频谱图 求已调信号功率、噪声功率等(Conventional AM modulation: Draw modulation waveform and spectrum before seeking modulated signal power, noise power, etc.)

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.)

用matlab对通信信号进行调制simulink仿真,它包括am,pm,fm,ask,psk,fsk,qpsk等调制方式(matlab simulink simulation ，contain：am,pm,fm,ask,psk,fsk,qpsk)

本程序是本人根据人脸识别PCA改进的，用于掌纹识别，是学习PCA特征提取的很好的学习资料。(I based this program is to improve the face recognition PCA for palmprint identification, PCA feature extraction is to learn a good learning materials.)
