一个三维的matlab FDTD 程序 ,从其他地方转载的(3d FDTD)

说明：  基于信噪比的QAM星座图算法描述，有很多星座图的相关知识及仿真(SNR of the QAM constellation based on algorithm description, there are many constellation of knowledge and Simulation)

performance comp of LMS with NLMS

this is a simple version of PRMA algorithm, a shared medium access protocol.

这个Matlab程序是关于OFDM调制的。这里使用了BPSK调制，显示OFDM在误码率上的下降。(This Matlab program is about OFDM modulation. Here the use of BPSK modulation, show the OFDM at BER on the decline.)

写的MATLAB程序实现傅里叶变换大家可与参考一下(MATLAB program written by Fourier transform we can refer to)

基于MATLAB的卷积交织编译码研究 基于MATLAB的卷积交织编译码研究(MATLAB-based encoding and decoding of convolutional interleaving MATLAB-based Encoding and Decoding of Convolutional Interleaver)

关于emd的判据研究，通过它可以终止emd对分平稳信号的分解，是最新版的方法(On the EMD criterion, it can terminate the EMD pair of stationary signal decomposition, is the latest version of the method)

这里面的是matlab代码，能够实现图像的分割和特征的提取，很实用(There is a matlab code to achieve segmentation and feature extraction of image，Very practical)

频谱分析说名太短，你这个破网站够可以了，一个分析小程序有啥好说嘛(Spectrum Analysis)
