计算地震引起库伦应力改变的程序，搞应力触发的可以看看(Calculated Coulomb stress changes caused by the earthquake process)

很好的粒子图像测速（PIV）Matlab源代码，本人在Matlab 2010下测试通过。(Particle image velocimetry (PIV) Matlab source code, I tested it using the Matlab 2010.)

The spectrum sensing problem has gained new aspects with cognitive radio and opportunistic spectrum access concepts. It is one of the most challenging issues in cognitive radio systems. In this paper, a survey of spectrum sensing methodologies for cognitive radio is presented. Various aspects of spectrum sensing problem are studied from a cognitive radio perspective and multi-dimensional spectrum sensing concept is introduced. Challenges associated with spectrum sensing are given and enabling spectrum sensing methods are reviewed. The paper explains the cooperative sensing concept and its various forms. External sensing algorithms and other alternative sensing methods are discussed. Furthermore, statistical modeling of network traffic and utilization of these models for prediction of primary user behavior is studied. Finally, sensing features of some current wireless standards are given.

卫星通信信道链路参数计算与模拟.由于降雨对不同频段下的卫星通信造成不同的衰减，通过计算与模拟卫星通信信 道链路参数，可以设计出可靠性更高的卫星通信系统。(Satellite communication channel link parameter calculation and simulation. Due rainfall in different frequency bands for satellite communications under different attenuation caused by calculation and simulation of satellite communication channel link parameters, you can design a higher reliability of satellite communications systems.)

说明：  该程序主要也是针对滤波器设计的，实现了对一个语音信号的滤波处理(The program is largely designed for the filter, the realization of a voice signal filtering)

分数阶fourior变换的源码，主要用来处理线性调频信号(fractional fourior transform source code, is mainly used to treat LFM)

　综合评判是对多种属性的事物，或者说其总体优劣受多种因素影响的事物，做出一个能合理地综合这些属性或因素的总体评判(Comprehensive evaluation of DuoZhong attributes of the things is, or the overall quality DuoZhong factors by the things, make a can be reasonably comprehensive these attributes or the overall evaluation factors )

matlab 编写的遗传算法程序，非常好用(genetic algorithm )

matlab写的神经网络的几个演示程序，有的是自己写的，有的是根据别人写的改的，bp、rbf、pnn、hopfield等(matlab neural network to write a few demo program, some wrote it myself, some other people to write in accordance with the change, bp, rbf, pnn, hopfield etc.)

利用matlab求QAM的一个程序实例，很实用(To seek QAM by matlab)
