MATLAB的部分源代码,与MATLAB数字信号处理与应用一书相配套(MATLAB source code of some)

简单的MATLAB对各种文件的读取，适合初学者入门学习使用。(Simple MATLAB to read the various documents, suitable for beginner to learn to use.)

说明：  用于信号滤波，要事先给出滤波器系数，给出心电加上正弦干扰信号的滤波过程。(For signal filtering, to filter coefficients is given in advance, given ECG+ sinusoidal interference signal filtering process.)

说明：  基于MATLAB/GUI的M-QAM调制解调及误码率,本文件是在MATLAB2009a版本上设计的，低于此版本的有可能会出错。 此文件中“M_QAM.m”是主文件，其他均为调用文件,该程序实现了MQAM的调制解调功能，并画出了每一步的波形 (Based on MATLAB/GUI s M-QAM modulation and demodulation and bit error rate, this document is designed MATLAB2009a version, this version is lower than might be wrong. This file is in the " M_QAM.m" is the main document, others are calling the file, the program implements the MQAM modulation and demodulation functions, and draw the waveform of each step)

基于主成分分解的波束形成，对于学习波束形成非常有帮助。(a good example for studying PCI beamforming.)

In this work, the Mel frequency Cepstrum Coefficient (MFCC) feature has been used for designing a text dependent speaker identification system. The extracted speech features (MFCC’s) of a speaker are quantized to a number of centroids using vector quantization algorithm. These centroids constitute the codebook of that speaker. MFCC’s are calculated in training phase and again in testing phase. Speakers uttered same words once in a training session and once in a testing session later. The Euclidean distance between the MFCC’s of each speaker in training phase to the centroids of individual speaker in testing phase is measured and the speaker is identified according to the minimum Euclidean distance. The code is developed in the MATLAB environment and performs the identification satisfactorily.
