求出运动目标回波信号的极值,运行时需找一个信号，并修改路径(The extreme value of moving target echo signal, runtime needs to find a signal, and modify the path )

很好的OFDM仿真程序代码，大家一起分享吧，祝大家分享愉快序，希望对大家有用。(OFDM simulation code well, we share it, I wish to share a happy sequence, we hope to be useful.)

Analog Filters Using MATLAB, 2009 很好的一本模电书，详尽描述了用Matlab设计模拟滤波器的方法，没有深奥的数学，非常棒！(The Analog the Filters Using MATLAB, 2009 good one mode power book, a detailed description of the design of analog filters using Matlab, not esoteric mathematics, great!)

利用matlab实现音乐合成的功能，合成了《东方红》，并且去除了啪啪声，此外对音乐的音色记性了各种改进。(Using matlab to achieve the function of music synthesis, synthesis " East is Red" , and removes pops, in addition to the sound of music memory various improvements.)

说明：  levy飞行改进pso,更好的pso改进措施，大家可以看看(levy_Flight to improve pso)

说明：  本人提交的用matlab的关于滤波器设计的作业，很有用的　(I used Matlab submitted on the design of filter operation, a very useful)

The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)
