基于BPSK的通信系统程序，上采样，平方根升余弦滤波器(Bpsk - based communication system program)

说明：  该文件详细的包含各类波束形成并进行了仿真(The file includes all kinds of beamforming in detail and is simulated.)

对图像进行欠采样，然后利用OMP 进行重构，其中用到了小波矩阵进行稀疏(The image is undersampled and then reconstructed by OMP, in which the wavelet matrix is used for sparsity.)

说明：  非负矩阵分解源代码,有经典NMF，LNMF,NMFsc,developped by patrik hoyer(Nonnegative matrix factorization LNMF,NMFsc,developped by patrik hoyer)

CDMA 系统仿真平台，有完整注释，对了解CDMA系统级仿真很有帮助(CDMA System Simulation)

a leach program for energy efficient network

说明：  详解莱斯信道与瑞利衰落信道，并将其对比，画出图形，便于理解(Rician channel and Rayleigh fading channel are explained in detail and compared Draw a figure, easy to understand)

说明：  WCDMA码分多址通信系统的matlab仿真以及结果(Matlab simulation and results of WCDMA code division multiple access communication system)

imnoise2,3，matlab实现噪声的函数，主要用于图片制造噪声，在学习频率域滤波时很有用(The function of MATLAB to realize noise;It is mainly used for picture making noise, which is very useful in learning frequency domain filtering.)

1）语音信号的采集 2）语音信号的频谱分析 3）设计高通、低通数字滤波器和画出其频率响应 4）用滤波器对信号进行滤波 5）比较滤波前后语音信号的波形及频谱 6）播放原始语音信号 7）实现快放、慢放功能 8）实现回音音效效果 9）实现变高音、低音效果 10）设计GUI系统界面 (1) voice signal acquisition 2) speech signal spectrum analysis 3) design high-pass, low pass digital filter and plot its frequency response 4) filtering the signal with a filter 5) to compare the before and after filtering the speech signal waveform and spectrum 6) Play the original voice signal 7) to achieve fast, slow function 8) to achieve an echo sound effect 9) to achieve change treble, bass 10) GUI system interface design)
