说明：  实现可见光通信的仿真，用OFDM的调制方式(VLC communication OFDM)

用Simulink中NCO模块产生正弦信号的程序，自己写的，采样率180MHz，正弦频率70MHz，可以直接运行。(Using Simulink module generates a sinusoidal signal of NCO program, sample rate 180MHz, sinusoidal frequency 70MHz, can be directly run.)

an algorithm is reproduced in own way to get optic flow pattern. horn schunck method is used.

利用matlab软件模拟平行光入射抛物线型曲面后反射的光路图。(It uses atalb software to simulate parallel light incident parabolic surface reflected light path diagram)

SER算法在自适应中的应用代码，其程序简单，但效果很好，可以和LMS算法做对比实验。(SER algorithms in adaptive application code, the procedure is simple, but the effect is very good, and the LMS algorithm to do comparative experiments.)

码分多址，是在无线通讯上使用的技术，CDMA 允许所有的使用者同时使用全部频带(1.2288Mhz)的系统仿真(CDMA is used in wireless communications technology, CDMA allows all users to simultaneously use all bands (1.2288Mhz) System Simulation)

这是我用matlab写的一个寻找凸包算法的实现，该算法是基于graham算法的一个改进(the source realize an improvement algorithm of searching convex hull which based on graham algorithm in matlab)
