扩频通信.第一本有关扩频系统的专著是R.C.Dixon于1976年出版，是一本IEEE专利，1977年出版。1978年在日本京都召开国际无线通信咨询委员会公布研究成果。1982年在美国召开第一次军事通信会议，两次报告在军事中的应用。1985年美国提出CDMA(码分多址)的概念同年美国联邦通信委员会(FCC)制定扩频通信的标准和规范，逐步转入民用的商业化研究-Spread Spectrum Communication. The first book on spread-spectrum systems is RCDixon monograph published in 1976, is an IEEE patent, published in 1977. In 1978 in Kyoto, Japan, an international wireless communications Advisory Committee published research results. 1982 in the United States held its first military communications conference, two reports in the military applications. The United States in 1985 proposed CDMA (Code Division Multiple Access) the concept of the same year the United States Federal Communications Commission (FCC) the development of spread spectrum communication standards and norms, and gradually transferred to the commercialization of civilian research

使用Jakes所假设的模型，用来产生信道抽头延迟线模型中的抽头增益过程所需的多普勒频谱成形滤波器有多种实现方法。时域FIR滤波器是最常用的一种实现方法。-Assumed the use of Jakes model, used to generate the channel-tap-tap delay line model of the process gain the necessary Doppler spectrum shaping filter has a variety of implementations. Time domain FIR filter is an implementation of the most commonly used method.

A self-designed control of PC parallel port communication is introduced in this paper.Taking advantage of the MFC ActiveX technology, it is developed in Visual C++ and offset the scarcity of the control of PC parellel paort communication. An example of frequency measurement shows the detail procedure and application of the control.

OFDM码与调制解调采用4-QAM。正交频分复用技术的代码，在整个范围内的工作状态。所使用的信道或者是AWGN信道。的BER（误码率）对SNR（信噪比），图形绘制。

该程序没有窗体，没有界面，点击即可运行，向指定的ip地址的端口发送udp协议的数据，且数据的类型不是文件，只是字符串。
