基于MATLAB 的语音信号频谱分析与去噪研究 1、通过Matlab读入语音信号，进行频域分析 2、绘制语音信号频谱； 3、设计滤波器并进行滤波； 4、加噪，对比语音信号波形和频谱(Research on speech signal spectrum analysis and denoising based on MATLAB 1, read the voice signal through Matlab and analyze it in frequency domain. 2, draw the frequency spectrum of speech signal; 3. The filter is designed and filtered. 4. Add noise and compare the waveform and spectrum of speech signal)

PCM clustering algorithm

best code for mimo-ofdm, basic for beginners, very benefical

ROC of Autocorrelation method. OFDM signal detection by Auto correlation method.

it is a very simple and helpful document and source code for image compression

说明：  mimo下行基于块对角化信道逆转的多用户预编码程序。(mimo downlink multi-user precoding based on block diagonalization channel inversion)

Wave Player With Effects And Analysis

在模式识别中，样本的特征选取是很重要的，大大的影响识别率，样本的特征提取(In pattern recognition, feature selection of samples is very important, and greatly affect the recognition rate, sample extraction)

BP人工神经网络的程旭，运行正常，按照需要修改参数即可(BP artificial neural network program, is operating normally, only need to modify the parameters)
