简单的数字传输系统---主要是对16-QAM数字基带传输系统进行仿真，基带调制和解调的输出信号都是复数信号。(Simple digital transmission system--- mainly simulate the 16-QAM digital baseband transmission system, the output signals of the baseband modulation and demodulation are complex signals.)

Principle Component Analysis

无线通信，信号通过qpsk调制，在高斯白噪声环境下的传输(Wireless communications, signal modulation by qpsk, white Gaussian noise environment in the transmission)

OFDM到AFDMA的映射（matlab）(OFDM to AFDMA mapping (matlab))

利用matlab编程实现RBF神经网络，利用训练模型算法，最后得到较精确的神经网络模型，里面的程序并不需要先前自己进行数据归一化处理(radial basis function)

用来计算旋转45度的矩形块的haarlike特征(Calculation rotated 45 degrees haarlike characteristics)

说明：  清华大学出版社，王岩编《数理统计与matlab》例题程序库(Tsinghua University Press, Wang Yan for &quot mathematical statistics with matlab&quot Example Library)

This program explain how FFT in Matlab works

说明：  matlab 做的仿真 SPWM 单相 全桥逆变(Matlab do simulation SPWM inverter single-phase bridge)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。(This program is the most basic particle swarm optimization procedures, using Matlab to achieve, is very simple.)
