Description: 随着计算机技术与通信技术日新月异的发展，无线局域网在个人和商业计算机 领域日益流行起来。随着用户的要求不断提高，无线局域网向更高频率、更宽带宽 的方向发展。IEEE802.11a/b/g是现在市场占有较大优势的无线协议标准，但是也越 来越不能满足无线局域网通讯的要求。IEEE802.11n标准是对802.11g的一场更新换 代。802.11n可以提供更高的传输速率，更广的覆盖范围，兼容802.11a/b/g。随着 频率的提高和带宽的增加还有协议的日益复杂性，射频前端的设计越来越不能脱离 数字基带的要求。计算机辅助分析和综合的工具还不能满足数字基带与射频部分的 联合仿真。所以，基于一定协议的射频电路的系统级设计的建模与仿真问题还有待 于开发。本论文基于最新无线局域网的IEEE802.11n草案标准，使用Matlab/Simulink 与MathCAD软件对射频前端电路进行建模和仿真，并建立数字基带联合仿真环境。

Description: NetTalk是一个适用于局域网和因特网的可视电话软件
一． 开发环境
Windows2000 Server & Visual C++6.0 & SDK
+自开发的CWndX类库(相当于简化的MFC涉及窗口的部分)
二． 支持环境
Windows98/ME/2000/XP
三． 所涉及协议和标准
网络传输采用UDP协议，音频压缩采用G.729标准，视频压缩采用H.263标准
四． 性能参数
以音频帧为基准，每帧音频数据有２４０个采样点，时间为２４０＊１０００／８０００＝３０ms，８０００为音频的采样率。
数据接收端队列缓冲延迟：３０＊3＝90ms
数据发送端录音延迟：30ms
数据压缩解压耗时：<40ms
网络延迟：<100ms（我想校网情况应该不错J）
总延迟：<260ms
根据VOIP标准，总延迟<300ms是人可以接受的，以上计算是保守的，实际情况可能会好得多。-NetTalk is applied to a LAN and the Internet a video phone software. Windows 2000 Server Development Environment

Description: 近年来，移动通信技术发展迅速，新技术层出不穷，
宽带无线接入技术由于具有网络设计灵活、安装迅速方
便、建设速度快、建设造价低廉等突出的优点，在高速因
特网接入、信息家电联网、移动办公、军事、救灾、空间
探险等领域具有非常广阔的应用空间。根据目前的技术
标准和将来的发展，主流的宽带接入技术可以分为：固定
宽带无线接入技术（FBWA）、无线局域网（WLAN）和无
线个域网（WPAN）。其中无线个域网的发展使得人们摆
脱电缆束缚，在近距离内实现各种设备间的通信的梦想
得以实现。基于ZigBee 无线接入技术的WPAN 更以其低
成本、低功耗等特有的优势成为无线接入领域的又一颗
璀璨的新星，给现代信息社会中人们的工作和生活方式
带来一场新的革命。-In recent years, mobile communication technology is developing rapidly, the new technologies have Broadband wireless access technology because of network design flexible, speedy and convenient installation, construction speed, construction of low cost highlight the advantages of high-speed Internet access, information appliances, networking, mobile office, the military, disaster relief, Space exploration and other areas with a very wide application of space. Under the current technical standards and future development, the dominant broadband access technology can be divided into : fixed broadband wireless access technology (FBWA) Wireless local area network (WLAN) and Wireless Personal Area Network (WPAN). Which WPAN development and enabled people to escape from cable restraints, In all wi
