基于matlab数字图像处理技术随书源代码第10章(Based on matlab digital image processing technology with the book source code Chapter 10)

orthogonal division multiplixing(ofdm) is a new scheme used in wireless communication systems its also called multicarrier system and achieved this. cyclic prefix is used to minimize the intersymbol interference(ISI) and intercarrier interference

这是一个针对采用三相三线制有源电力滤波器的matlab仿真model，采用一种带积分的位置跟踪滑模控制方法，实现电源电流的追踪控制。(This is a simulation model for the three-phase three-wire active power filter matlab, using a position tracking with integral sliding mode control method to achieve supply current tracking control.)

OFDM PAPR Reduction for B3G or 4G mobile wireless communication system.

this is simple qpsk for matlab code

基于Ncut谱聚类的例子，其中包含了SVM代替k-means的方法进行后续分类。(Example of Ncut spectrum clustering .)
