信号与系统在MATLAB中的实现，给出了各种信号处理基本方法的源码实现(Signals and Systems at the MATLAB implementation, give a variety of basic methods of signal processing implementation of the source)

Kalman filter simulation on Matlab code

本程序用于Matlab对DAT格式的心电信号进行读出的功能(This procedure for Matlab on ECG DAT format to read out the functions of)

服从频率选择性衰落并且也服从瑞利衰落的信道。(Subject to frequency selective fading and also subject to Rayleigh fading channel.)

CDMA PROGRAM SIMULINK33

a very good book by bentley about transeducer technology useful inPG course

包括CRC,卷积码，RS码以及TCM码的matlab程序(include CRC check,convcode,RScode and TCMcode.)

说明：  根据滤波器指标选择合适的窗函数，计算窗函数的长度N，调用MATLAB函数fir1设计一个FIR低通滤波器。并编写程序，调用MATLAB快速卷积函数fftfilt实现对xt的滤波。绘图显示滤波器的频响特性曲线、滤波器输出信号的幅频特性图和时域波形图。  (Select the appropriate indicators according to filter window function, calculate the length of window function N, called MATLAB function fir1 design a FIR low-pass filter. And programming, call MATLAB functions fftfilt achieve fast convolution filtering xt. Graphics filter frequency response curve, the filter output signal amplitude and frequency characteristics of maps and time-domain waveform.  )

this is a small program that I use for some researches

画出每个IMF分量及最后一个剩余分量residual的图形 画出每个IMF分量及剩余分量residual的幅频曲线 用Hilbert变换直接求该信号的瞬时频率 计算HHT时频谱和边际谱(Draw each IMF component and the last one remaining residual component graphics draw each IMF component and the amplitude of the remaining component of the residual frequency curve directly seeking the instantaneous frequency of the signal with the Hilbert transform spectrum and marginal spectrum calculation HHT)
