NS2 无线传感网络（Leach协议）

粒子群优化算法(PSO)是一种进化计算技术(evolutionary computation)，有Eberhart博士和kennedy博士发明。源于对鸟群捕食的行为研究 PSO同遗传算法类似，是一种基于叠代的优化工具。系统初始化为一组随机解，通过叠代搜寻最优值。但是并没有遗传算法用的交叉(crossover)以及变异(mutation)。而是粒子在解空间追随最优的粒子进行搜索。详细的步骤以后的章节介绍 同遗传算法比较，PSO的优势在于简单容易实现并且没有许多参数需要调整。目前已广泛应用于函数优化，神经网络训练，模糊系统控制以及其他遗传算法的应用领域(Particle Swarm Optimization (PSO) is an evolutionary computation technique (evolutionary computation), has Dr. Eberhart and Dr. kennedy invention. Deriving from the behavior of birds of prey PSO with genetic algorithm is similar to an iterative optimization-based tools. System initialization for a group of random solutions, through the iterative search for optimal values. But there is no cross-genetic algorithm used (crossover) and mutation (mutation). But the particles in the solution space of the particles to follow the optimal search. In detail the steps after the introduction sections compared with the genetic algorithm, PSO has the advantage of being simple and easy and did not realize many of the parameters need to be adjusted. Has been widely applied to function optimization, neural network training, fuzzy system control, as well as other genetic algorithm applications)

在有多普勒扩展的情况下，产生一个FIR滤波器。(Generates a FIR Jakes filter for a given Doppler spread)

是机器学习的例程，包含收发两个客户端的链路级通信程序,通过matlab代码，LCMV优化设计阵列处理信号，有信道编码，调制，信道估计等，均值便宜跟踪的示例。 ( Machine learning routines, Contains two clients receive link-level communications program, By matlab code, LCMV optimization design array signal processing, Channel coding, modulation, channel estimation, Example tracking mean cheap. )

D2D通信分为集中式控制和分布式控制。集中式控制由基站控制D2D连接，基站通过终端上报的测量信息，获得所有链路信息，但该类型会增加信令负荷(D2D communication is divided into centralized control and distributed control. Centralized control is connected by the base station. The base station obtains all link information through the measurement information reported by the terminal)

这是一些基本的滤波程序，包括卡尔曼，以及扩展卡尔曼滤波，可以用于跟踪目标，航迹关联(This is some basic filtering procedures, including the Kalman and extended Kalman filter can be used to track the target, track correlation)

用matlab程序来实现一首流行歌曲的演奏和播放(Matlab program to a pop music concert and play)

借鉴于光子晶体的平面波展开法。通过把弹性常数、密度等参数按傅里叶级数展开，并与bloch定理结合，将弹性波波动方程在倒格矢空间以平面波叠加形式展开。该程序就是其具体的实现。标注详细，易于理解！
