The goal of this thesis is the development of traffic engineering rules for cellular packet radio networks based on GPRS and EDGE. They are based on traffic models for typical mobile applications. Load generators, representing these traffic models, are developed and integrated into a simulation environment with the prototypical implementation of the EGPRS protocols and models for the radio channel, which were also developed in the framework of this thesis. With this simulation tool a comprehensive performance evaluation is carried out that leads to the traffic engineering rules.

二次雷达(Secondary Surveillance Radar)是民航空中管制(Air traffic Control)和军事敌我识别(Identification Friend or Foe)系统中的关键部分,由于这两个应用领域都要求很高的可靠性和稳定性,因此,二次雷达一直是国内外雷达信号处理领域的研究热点.传统的机载二次雷达应答器普遍采用中小规模集成电路和分立元件设计,其稳定性和可靠性差,实时处理能力也很有限,无法完成高密度、大容量的应答.针对这些缺陷,本论文提出一种全新的应答数字信号处理器硬件结构,即FPGA+DSP的混合结构.这种硬件体系结构的特点是可靠性高,集成度高,通用性强,适于模块化设计,处理速度快,能实时处理多个应答信号,以及进行置信度分析和生成报表.此项目中,本文作者主要负责FPGA部分硬件设计.FPGA主要完成双通道数据采集、产生视频信号和旁瓣抑制信号、计算当前飞机相对本地接收天线的方位和距离、与DSP实时交换数据、上传报表等功能.论文详细分析了接收机信号处理算法在FPGA中的硬件实现方案,在提高系统可靠性、坚固性以及FPGA资源的合理利用方面做了深入的探讨.同时给出不同层次关键模块的HDL实现及其时序仿真结果.

在汽车发动机起动时，若发动机起动后起动机不能及时断电，将会烧毁起动机或损坏飞轮齿环；若变速器不在空档位置起动，则起动机的瞬间动力将使汽车位移，还可能引起交通事故和人身安全。为此介绍一种利用NXP P89LPC901单片机控制的汽车起动保护控制器，通过检测汽车起动开关、变速箱档位、发动机转速，实现对汽车发动机起动过程检测和保护。起动保护控制器在发动机起动过程中通过采用逐个关闭打开负载系统，解决汽车发动机过程中因起动电流大而对汽车电源的冲击影响,延长了电瓶寿命。 Abstract: When the automotive engine is started, the engine start motor and flywheel gear may be damaged， even traffic accidents and personal safeties may be caused by wrong operation or other factors.In order to ensure the automotive engine can be started normally and safely,it is necessary that the protecting measures and methods are considered in the automotive electrical control system.This paper introduces a kind of the automotive engine starting protect controller based on NXP P89LPC901 MCU.The controller can protect the engine starting process by detecting the starter key switch,transmission stall and engine speed.Through the use of close and open load system,the controller can solve the impact on automotive power because of the high-current load in the process of the automobile engine starting, and extend battery life.

The goal with this project was to make it possible for almost any mobile-phone to use ICQ and be able to communicate with other users! One other goal with this project was to lower the GPRS-traffic in the phone and make the ICQ-ing cheaper. A third goal was to make this service as easy to log-in to as possible. Anyone tried to fill a log-in screen with a WAP-browser should know what I mean. With Wapmess all you have to do is to write your login-url ONCE and then bookmark it in your phone, to make it available fast. :)
