说明：  认知无线电技术的提出是为提高频谱利用率，而认知无线实现的关键技术是频谱感知，众所周知协作检测提高了衰落环境中认知用户系统检测的性能，该文章是基于协作检测提出新的检测方案，利用了双门限方法提高了系统性能，兼顾带宽有限和增强性能两个方面，是基于门限检测的协作检测性能优化的前提。对以后门限优化协作检测非常有用。(In this paper, we employ a double threshold method in energy detector to perform spectrum sensing, while a fusion center in the cognitive radio network collects the local decisions and observational values of the secondary users, and then makes the final decision to determine whether the primary user is absence or not. Simulation results will show that the spectrum sensing performance channels is improved significantly under the proposed scheme as opposed to the conventional method.)

This file contains codes for simulating BPSK modulation with Monte Carlo methos. it is so useful for calculating BER in communication systems.

基本粒子群优化算法Matlab源程序 网上找到的别人做的很简单的程序，写的很精练很工整，据说优化效果不是很理想，由于没有时间去做很多测试，所以就先摆在这里，但愿以后能用得上。 下面是主函数的源程序，优化函数则以m文件的形式放在fitness.m里面，对不同的优化函数只要修改fitness.m就可以了通用性很强。 (Particle Swarm Optimization Algorithm Matlab source code online to find others to do the procedure is very simple, very concise writing is very neat, is said to optimize the effect is not very satisfactory, because there is no time to do a lot of testing, so I have to put in here, I hope that can use later. The following is the main function of the source, optimizing the function form of the document on Zeyi m fitness.m inside, as long as the different optimization functions can modify the fitness.m highly generic.)
