basic-OFDM

本代码使用matlab工具实现了一幅图片的位面图提取，且实现了在某个位面上加密信息、恢复信息的功能。并给出三幅图片的运行结果展示。(This code uses the matlab tool to achieve a picture of the bit plane map extraction, and the realization of the encrypted information in a bit plane, the function recovery information. And gives the results of running three pictures show.)

这是一个基于matlab应用于电力潮流计算的ieee14节点模型(This is a matlab in power flow calculation based on the ieee14 node model)

离焦系统的OTF曲线的matlab仿真 包含：1.不同波像差时，圆孔离焦的OTF及 2.不同波像差时，圆孔离焦下余弦光栅的像对比(Matlab simulation of the curve away from the focus system OSF)

该程序使用matlab模拟出心电图信号。(The program uses matlab simulate the ECG signal.)

说明：  RS的编码就是计算信息码符多项式，除以校验码生成多项式之后的余数；rs编码的基本实现，包括add,mul函数等；(RS coding is to calculate the information symbol code polynomial, divided by the check code generator polynomial after the remainder rs basically coding, including add, mul function, etc. )

说明：  

这个是我自己编写的基于混沌自适应粒子群优化的matlab程序,得出了非常好的效果!(This is what I have written based on adaptive particle swarm optimization chaos matlab program, obtained very good results!)
