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)

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.

中文摘要 正交频分复用（ OFDM ， Orthogonal Frequency Division Multiplexing）是当前一种非常热门的通信技术。它即可以被看作是一种 调制技术，也可以被看作是一种复用技术。由于它具有抗多径衰落和频谱 利用率高的特点，因此被广泛应用于高速数字通信领域，比如应用于IEEE 802.11a无线局域网（WLAN）的物理层等等。 我的毕业设计的核心任务是：采用 FPGA 来实现一个基于OFDM 技术 的通信系统中的基带数据处理部分，即调制解调器。其中发射部分的调制 器包括：信道编码（Reed-Solomon 编码），交织，星座映射，FFT和插 入循环前缀等模块。我另外制作了相应的解调器，可以实现上述功能的逆 变换。 另外，我还对OFDM技术， IEEE 802.11a的标准文献，基于Simulink 的 OFDM 模型和仿真，ALTERA 公司的技术和 IP Core 的使用等方面进 行了研究。这些在文章中都有体现。 (Abstract Orthogonal frequency division multiplexing (OFDM, Orthogonal the Frequency Division, Multiplexing) is a very popular communication technology. It can be seen as a Modulation technique can also be seen as a multiplexing technique. Because of its resistance to multipath fading and spectrum High utilization characteristics, and is widely used in high-speed digital communications, such as used in IEEE 802.11a wireless LAN (WLAN) physical layer. The core mission of my graduation project: FPGA to implement a technology based on OFDM Communication systems in baseband data processing part, ie the modem. These emission part of the modulation Includes: channel coding (Reed-Solomon coding), interleaving, constellation mapping, FFT and interpolation Into the cyclic prefix modules. I also produced a corresponding demodulator can achieve the inverse of the above functions Transformation. In addition, OFDM technology, the IEEE 802.11a standard literature, based on Simulink )
