    Memory allocation in C Dynamic memory allocation and the structures that implement it in C are so universal that they re sometimes treated as a black box. In the real world of embedded systems, that may not be desirable or even possible.

    Java technology has evolved from a programming language designed to create machine-independent embedded systems into a robust, vendor-independent, machine-independent, server-side technology, enabling the corporate community to realize the full potential of web-centric applications. Java began with the release of the Java Development Kit (JDK). It was obv

    A large body of computer-aided techniques has been developed in recent years to assist in the process of modeling, analyzing, and designing communication systems . These computer-aided techniques fall into two categories: formula-based approaches, where the computer is used to evaluate complex formulas, and simulation-based approaches, where the computer is used to simulate the waveforms or signals that flow through the system. The second approach, which involves “waveform”-level simulation (and often incorporates analytical techniques), is the subject of this book. Since performance evaluation and trade off studies are the central issues in the analysis and design of communication systems, we will focus on the use of simulation for evaluating the performance of analog and digital communication systems with the emphasis on digitalcommunication systems.

  • A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM)

    A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication systems. This program is valuable for future researchers simulating systems that are too theoretically complex to analyze. Single-carrier QAM and multicarrier OFDM are compared to demonstrate the strength of OFDM in multipath channels. Two graphical user interface demonstrations show some of the basic concepts of OFDM.

  • PSCAD实验指导教程

    PSCAD/EMTDC是加拿大马尼托巴高压直流研究中心出品的一款电力系统电磁暂态仿真软件,PSCAD(Power systems Computer Aided Design)是用户界面,EMTDC(Electromagnetic Transients including DC)是内部程序。 EMTDC最初代表直流暂态,是一套基于软件的电磁暂态模拟程序。Dennis Woodford博士于1976年在加拿大曼尼托巴水电局开发完成了EMTDC的初版,编写这个程序的原因是因为当时现存的研究工具不能够满足曼尼托巴电力局对尼尔逊河高压直流工程进行强有力和灵活的研究的要求。自此之后程序被不断开发,至今已被广泛地应用在电力系统许多类型的模拟研究,其中包括交流研究,雷电过电压和电力电子学研究。EMTDC开始时在大型计算机上使用。然后在1986年被移植到Unix系统和以后的PC机上。 PSCAD代表电力系统计算机辅助设计,PSCAD的开发成功,使得用户能更方便地使用EMTDC进行电力系统分析,使电力系统复杂部分可视化成为可能,而且软件可以作为实时数字仿真器的前置端。可模拟任意大小的交直流系统。PSCAD V1 1988年首先在阿波罗工作站上使用,然后大约在1995年PSCAD V2开始应用。PSCAD V3以PC Windows作为平台,在1999年面世。目前最新版本的是PSCAD V4.2.1。 用户可以通过调用随EMTDC 主程序一起提供的库程序模块或利用用户自己开发的元部件模型有效地组装任何可以想象出的电力系统模型和结构。EMTDC 的威力之一是可以较为简单地模拟复杂电力系统, 包括直流输电系统和其相关的控制系统。 采用 PSCAD/EMTDC 进行的典型模拟研究包括:  一般的交流电力系统电磁暂态研究  直流输电结构和控制  FACTS(灵活交流输电系统)元部件模型  由于故障、断路器操作或雷电冲击引起的电力系统的过电压研究  绝缘配合研究  谐波相互影响研究  静止补偿器研究  非线性控制系统研究  变压器饱和研究, 如铁磁振荡和铁芯饱和不稳定性研究  同步发电机和感应电动机的扭矩效应和自励磁研究  陡前波分析  研究当一台多轴系发电机与串补线路或电力电子设备相互作用时的次同步谐振现象  向孤立负荷送电 电力系统数字仿真实验室使用PSCAD/EMTDC主要进行一般的交流电力系统电磁暂态研究,进行简单和复杂电力系统的故障建模及故障仿真,分析电力系统故障电磁暂态过程。
