wuyufei的turbo程序，做turbo的人一定要看的matlab程序。(wuyufei the turbo procedure, turbo make sure to look at the matlab program.)

利用最优信息二分割法分析变异点，用于水文计算，流量、降雨等(Optimal information two split method of analysis of variance points)

自己写的matlab写的细化程序，特别针对条形的图形(Matlab write their detailed written procedures, especially for bar graph)

在AWGN信道模型下，对比ACO-OFDM和其他调制方式对光纤通信系统性能，将ACO-OFDM与一些调制技术相结合来进一步提高系统宽带效率、降低光发送功率等，以提升光纤通信系统的性能(In AWGN channel model, compared to ACO-OFDM and other modulation schemes for optical fiber communication system performance, the ACO-OFDM with some modulation techniques combined to further improve the system broadband efficiency and reduce light transmission power so as to enhance the performance of optical fiber communication systems)

lcs码系统仿真，matlab7.0编译通过，通过仿真可以了解不同参数下，信号衰耗程度(lcs Code System Simulation, matlab7.0 compiler is passed, through the simulation can understand the different parameters, the degree of signal attenuation)
