代码说明:

  提出了一种认知无线网络的异构网络融合的研究方案。该方案采用了具有可重构能力的基站设备和多频段多模式终端设备 , 采用复用的方式来达到多频段变换的目的 , 并最终提高无线资源利用效率。以中间件的方式来实现各种通信模式的融合和切换 , 并设计了基站分布式天线 , 来满足更大的负载或更 高的业务质量需求。建立了一个基于软件无线电的终端系统 , 该终端的优点在于其可以工作在多个频段之上 , 并且可以自适应的工作在多种不同模式的网络中。(cognitive wireless networks in)

    This paper presents a clustering approach which estimates the specific subspace and the intrinsic dimension of each class. Our approach adapts the Gaussian mixture model framework to high-dimensional data and estimates the parameters which best fit the data. We obtain a robust clustering method called High- Dimensional Data Clustering (HDDC). We apply HDDC to locate objects in natural images in a probabilistic framework. Experiments on a recently proposed database demonstrate the effectiveness of our clustering method for category localization.

    本文在分析城市交通信号控制研究现状和交叉口交通信号控制原理、评价方 法的基础上,设计了单交叉口交通信号两级模糊控制系统。分级模糊控制能有效 减少模糊规则数,易于提取模糊规则,适合于交通状况复杂的城市交叉口交通信 号控制。但它存在难以由人工合理定义全部模糊隶属度函数的问题。为此本文进 一步采用遗传算法对两级模糊控制器中模糊隶属度函数进行优化。本文提出的方 法具有分级模糊控制的优点,同时可以使模糊隶属度的选取更为合理,获得更好 的控制效果。对一个四相位单交叉口,利用MATLAB在不同的交通条件下进行 了仿真,并利用交通仿真软件PARAMICS进行了可视化仿真。仿真结果表明该 方法能有效降低通行车辆在交叉口的平均等待时间,明显优于传统控制方法(After analyzing the city-traffic developments,the grade crossings control theory its method of evaluation,the paper designs a traffic signal two-stage fuzzy control tem for single intersection.Two-stage fuzzy controller,which is easy to acquire zy rules and can greatly decrease the number of fuzzy rules,is very suitable to plex urban intersection control.But it still presents a difficulty for deciding all the bership functions correctly only by human experience.Therefor,to solve this blem,a technique using genetic algorithm to modify its fuzzy membership ctions is proposed.This method not only possesses the advantages of hierarchical zy control,but also can change its membership functions adaptively to an optimal ing in different traffic situations as well,and in this way the currency power of the an intersection is improved.For a single urban intersection with four-phase, ulation of different traffic condition is processed by using MATLAB.Moreover, ble simulation is proce)
