OFDM仿真程序MATLAB 接收端采用的算法和程序流程与发送端发送的OFDM符号的帧结构有关系。具体的帧结构，以及定时估计，频偏估计，剩余误差跟踪的算法可参考算法说明文档(MATLAB simulation program OFDM receiver algorithm and procedures used in processes and the sending end to send the frame structure of OFDM symbols are. Concrete frame structure, as well as the timing estimation, frequency offset estimation, the remaining error tracking algorithm algorithm can refer to documentation)

在Juan Cardelino发布的FMM(fast marching methos)2维程序基础上改写的3维程序。并改写成适合复杂速度模型，可用于地震旅行时计算。大模型3d算法在matlab下计算速度较慢，根据源码中的注释很容易改写成c程序。(3D FMM program revised from Juan Cardelino s 2D version. The program can calculate the seismic traveltimes in 3D complex model)

美国德克萨斯州大学电子工程系开发的一套进行语音分析的MATLAB程序． A MATLAB software tool for speech analysis．(University of Texas, Department of Electronic Engineering, developed a voice analysis of MATLAB. A MATLAB software tool for speech analysis.)

turbo 编译码，采用网格编码调制方式，并且成功地在大气激光通信中得到应用。调制部分自己编写，可直接运行，有助于学习turbo-TCM。都是压缩包形式，里面有多个程序和函数。(turbo encoding and decoding, using trellis coded modulation, and successfully applied in atmospheric laser communication. Modulated part of their preparation, can be run directly, will help you to learn turbo-TCM.)

求满足巴特沃斯模拟低通的最低结束以及滤波器系统函数及其几点位置(To meet the butterworth lowest end and analog low-pass filter system function and its several location)

本程序实现了基带蒙特卡罗仿真,分析了基带误码性能。(This program simulates a Monte Carlo system to obtain a BER )

Kmedoid 是类似于Kmean的Clustering method。(Kmedoid is similar to Kmean the Clustering method.)
