AC-DC-AC双pwm逆变器的Matlab/Simulink仿真源程序。包括两个电路：一个是50Hz三相 AC(PWM整流)->DC->50Hz三相AC(PWM逆变),驱动三相对称电阻负载；一个是60Hz 三相AC(全波整流)->DC->50Hz三相AC（PWM逆变），驱动一个永磁同步电动机。（本源码基于王军(xiaohongchen@163.com)上载的double_pwm_inverter.mdl改进而来，适用于matlab7.3.0(R2006)版本）(AC-DC-AC inverter pwm dual Matlab/Simulink simulation source. Includes two circuits: one is the 50Hz three-phase AC (PWM rectifier)-)

Simulator for a GSM traffic channel transmission and reception This Simulink model simulates the entire transmission and reception of voice data of a traffic channel for GSM (TCH/FS)over a multipath fading channel, and it calculates the BER of the received signal(Simulator for a GSM traffic channel transm ission and reception This Simulink model simul ates the entire transmission and reception of v oice data of a traffic channel for GSM (TCH/FS) o ver a multipath fading channel, and it calculates the BER of the received signal)

图像处理基础算法源代码MATLAB集合，里面很多修改就可以用(Image Processing MATLAB based algorithm source code set, which can be used to modify many)

一个完整的EMD程序，附带了G Rilling的附件，适合新手学习使用。(A complete EMD procedures, suitable for novice learning to use.)

说明：  求x的算术平方根，保留N位有效数字，并返回算术平方根的平方(solving the square root of x with N digits Significant figures, and saving the Square root of the square)
