语音水印算法的matlab 编程实现，毕业设计，基于小波，到谱分析(Audio Watermarking Techniques implemented by the MATLAB PROGRAMMING)

给出了三个m文件，分别适用于不同的Shortestpath问题，本程序是工程CT的一部分，属于正演算法，可获得射线路径。每一条均有注释，适合初学者。完美运行。(For the Shortpath, given 3 m files. They are the part of CT for induction. Fit for green hands.)

自己编写的基于小波变换的matlab算法，希望对大家有所帮助(I have written matlab algorithm based on wavelet transform, I hope to be helpful)

自由空间光通信系统在大气湍流信道下的3个主要性能指标分析，即平均误码率、中断概率和平均信道容量。其中大气湍流采用gamma-gamma湍流信道衰退模型。3个M文件为平均误码率与平均信噪比之间的关系(BER_SNR.m)，中断概率(OutageP.m)，以及平均信道容量与平均信噪比之间的关系（C_SNR.m）。程序可直接运行。(The analysis of 3 key performance indicators of Free-Space Optical communication system in atmospheric turbulent channel, namely the average bit error rate, outage probability and the average channel capacity. The atmospheric turbulence is modeled by the gamma-gamma turbulent channel fading model. Three M-files are the relationship between the average bit error rate and the the average SNR (BER_SNR.m), outage probability (OutageP.m), the relationship between the average channel capacity and the average SNR (C_SNR.m).The programs can run directly.)

关于高阶累积量时延估计方法的研究，本代码描述的是三阶累积量，广义相关法，进行了两者性能相关的比较，最终能求得试验估计值，比较出两者的性能。(The cumulative amount of higher order time delay estimation method studies, the code describes the third-order cumulant, generalized correlation method were compared between the two performance-related, the final test estimate can be obtained, to compare the performance of both.)

对信道估计LS算法和MMSE算法的误码率比较(comparison of LS and MMSE )
