经典的瑞利衰落信道仿真模型-jakes模型。程序可以修改不同的入射路径个数。仿真结果是不同入射路径个数的jakes模型和同分布的瑞利衰落的包络分布对比。直接运行“tu.m”(The classic Rayleigh fading channel simulation model-jakes model. Program can modify the number of incident path. The simulation results compare jakes model of different incident paths with distribution of Rayleigh fading.)

用均匀线阵进行DOA估计，空间平滑法，Toeplitz法，music法(With a uniform linear array DOA estimation, spatial smoothing method, Toeplitz law, music)

用matlab进行图像处理程序，可对图像进行对比度、灰度处理。(Matlab image processing procedure, but the image contrast, gray processing. )

在阵列天线自适应信号处理中，经常会出现因为阵元位置信号角度估计等误差引起的，天线性能急剧下降的问题，在此运用稳健性的方法提出一种稳健的自适应阵列天线波束合成方法，来解决此问题(In the adaptive array antenna signal processing, often occur because the sensor position signal angle estimation error caused a sharp decline in the performance of the antenna problem, a robust adaptive array antenna beam synthesis method in this application of the robustness of the method to solve this problem)

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)
