现代通信系统第6章 matlab程序源码(Modern communications systems Chapter 6 procedures for source code matlab)

做一个特征提取的模拟。功能良好。非常实用(To make a feature extraction simulation. Good function. Very useful)

本程序是主成分分析，可以解决几个几个输入之间的相关性，能够提取出多输入的主成分(This program is the principal component analysis can solve several several input correlation between the principal components can be extracted multiple input)

一个ＤＣＴ函数的程序，和滤波器，ＭＡＴＬＡＢ信号的产生(a function of processes, and to filter, the signal generated MATLAB)

chi-square testing for lognormal distribution

Garbor filter matlab implementation

说明：  络检波法，也可以用同步解调法，现在我们来使用同步解调法，即将已调信号和一个与载波信号同频率的信号相乘，在通过一个理想低通滤波器就可以得到原始信号(Envelope detection method, you can also use synchronous demodulation method, and now we use synchronous demodulation method, is about modulated signal and a signal is multiplied with the same frequency of the carrier signal, through an ideal low-pass filter can get the original signal)

matlab在统计等方面运用 MFE_Toolbox(matlab statistics MFE_Toolbox)

对qpsk在高斯信道条件下合瑞利先到条件下的误码率进行了仿真(On the Gaussian channel in qpsk conditions together under the conditions of Rayleigh first simulated bit error rate)

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