根据 DVB-T 欧洲标准写的一个OFDM matlab 仿真，其中包括发射器和接收器。文章中有matlab程式的详细介绍，有仿真方框图，还有每步的实验结果分析，特别适合OFDM的初学者。算是OFDM比较简单的一个入门介绍。英文也比较浅显，可读性很强(According to the European DVB-T standard to write a OFDM matlab simulation, which comprises a transmitter and a receiver. Article has a matlab program in detail, there is a block diagram of the simulation, as well as analysis of the experimental results of each step, especially for OFDM for beginners. OFDM considered a relatively simple introduction to. English is also relatively simple, readable)

该程序实现了压缩感知理论中采用矩阵的优化。在压缩感知理论中，要求采样矩阵与稀疏矩阵的相关性越低越好。该代码采用一种交替投影的方法实现采用矩阵的优化，有效降低其相关性。(The program to achieve the optimization of the use of matrix theory compressed sensing. Requirements of the sample matrix and sparse matrix theory of compressed sensing, the lower the better. The code uses an alternating projection method to achieve the optimization of the use of matrix to effectively reduce the correlation.)
