This file contain the Simulation of a Cognitive Radio System by Using Matlab Software.Also This file containing a guide file to explain how the code is work.

采用matlab来检测肤色区域，其他区域置为灰色，一个很简单的程序，基于RGB颜色空间(skin color detection)

对matlab的指令和函数进行了详细说明和解释(On the matlab function instructions and a detailed description and explanation)

说明：  基于Matlab的JPEG图像压缩编码仿真，我们在JPEG图像压缩原理的基础上，用Matlab对标准的灰度图像进行JPEG压缩与重建。(Based on the JPEG image compression coding Matlab simulation, we JPEG image compression based on the principle of using Matlab on a standard gray scale images and reconstruction of JPEG compression.)

Pulse code modulation matlab code

说明：  这些matlab程序不错，希望大家能有时间能看下。(The matlab program good, hope that we can have time to be able to Kanxia.)

粒子群优化算法（可以应用在寻优建模过程中）(Particle Swarm Optimization (can be applied in the modeling process optimization))
