说明：  最近在研究脑电信号的处理 同事自己也收集了一些资料希望和大家分享(Recent studies dealing with EEG colleagues collected themselves would like to share some information)

实现直接序列的扩频通信，其中仿真波形很形象的反应扩频的各个部分，pn码等等(Realize the direct sequence spread spectrum communication, which is the reaction of the waveform image of spread spectrum all part of pn code, and so on )

MATLAB CODE FOR INFORMATION THEORY AND CODING

A matlab script to generate scatter plot for the M-ary Modultaion. it asks user to input the value of: M-ary, SNR(in db), number of binary carriers

微粒群的二维演示，pso_2D，对初学者有一定的帮助！！！！！(Two-dimensional demonstration of particle swarm, pso_2D, must have for beginners help! ! ! ! !)

说明：  录制一段个人的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用双线性变换法和窗函数法设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Record a personal voice signal, and recording the signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum for a given filter performance, the bilinear transformation and design of filter window functions and draw the frequency response filter then filter of their own design collection of the signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, analysis of signal changes playback audio signals Finally, a signal processing system interface design.)
