无线通信中，瑞利信道的仿真，考虑到了多普勒频移，还有信号的调制，编码等(Wireless communication, Rayleigh channel simulation, taking into account the Doppler shift, as well as signal modulation, coding, etc.)

本程序利用显式差分格式，将波动方程离散化，进而求出波动方程的数值解，不断地细化空间和时间步长，可以让数值解逼近理论解。(The program with the implicit difference method, the discrete wave equation, the numerical solution is obtained, continue to refine the long walk the numerical solution can approach the theoretical solution.)

this is used to extract the leaf vein

CEEMD算法文件，已经过测试，可完全能够使用！！！(CEEMD algorithm file)

基于standford大学cioffi教授的经典算法，计算有线信道的无限冲击响应滤波器系数。(Based on algorithm proposed by Prof. Cioffi, calculate the optimal IIR coefficients for cable channel.)

this codes about design antenna dipole in MIMO.The implementation is based on the earlier implementations of WINNER II interim model [

在matlab中利用平方环实现QPSK信号的码元同步，可实现，效果较好。(Square ring QPSK signal symbol synchronization can be achieved in matlab better.)

ART2网络的MATLAB程序，自己编写的。最近一系列的文章都是用这个作的实验。在科学网可以找到本人博客下载相关论文(ART2 network MATLAB procedures, I have written. The recent series of article are made using this experiment. Net can be found at science blog I download related thesis)

matlab code for perceptron and its results

经典的二阶矩四阶矩信噪比估计，有不经过上采样、成型滤波和经过上采样、成型滤波的两种版本。加噪方式也分别用了matlab自带函数和自写两种版本。望大家参考。(Second Moment classic SNR estimation fourth moment, there is not through the sampling, the shaping filter and sampled, two versions of shaping filter. Plus noise mode were also comes with a matlab function and self-written versions. Hope you reference.)
