说明：  空气悬架天棚控制系统，使用简单有效，推荐(Air suspension ceiling control system, simple and effective to use, recommended)

QPSK调制代码,高斯和瑞丽衰落信道后的信号波形(QPSK　Modulation)

说明：  这是一个关于MATLAB的函数，能够用DEMO打开；使用时首先解压然后转换为M文件即可。很方便的。(It is a MATLAB function, can open the DEMO use first and then converted to M-extracting files. Very convenient.)

在转速为48K/min时，外圈故障的几个时域波形(In speed for 48 k/min, rolling body several time domain waveform )

this code fo fuzzy template

这个是tabu 搜索算法， 用matlab实现，有助于学习tabu算法的人(it is the TABU algorithm)

一种采用matlab编程的surfacelet示例程序，来自官方主页(a demonstration version of surfacelet transform compression programmed in MATLAB language)

ofdma的一个简单的收发程序采用QPSK调制噪声是高斯白噪声(A simple transceiver of ofdma program using QPSK modulation noise is gaussian white noise)

通信系统，基于MATLAB对OFDM进行仿真，结果有调制解调图，信噪比，眼图等等。( Communications systems, based on OFDM MATLAB simulation results have modem map, SNR, eye and so on.)
