一种扩频通信系统模型设计

移动通信的发展当前正处于一个关键时期,新的业务和技术不断涌现,客户的需求也不断增长。同时,因特网迅速发展成为真正的超级高速公路,数据多媒体通信发展迅猛,所以第三代移动通信的目标是宽带通信,也就是扩频通信。本文讨论了多相正交序列波应用于扩频通信系统的可能性。构造了基于多相正交序列波的扩频通信系统模型,并用Simulink软件对其通信过程进行仿真。结果表明,接收端恢复的信息数据保持了发送端信息数据的特征。

Model Design of a Spread Spectrum Communication System

Mobile communication is in a key period of development. New operation and technology are coming forth. At the same time, Internet is being a true information high way and multimedia is developing rapidly. Therefore, the target for third generation mobile communication is spread spectrum communication. In this paper, spread spectrum signal used in communication system direct- ly is introduced. A model of communication system using the signal is given, and the simulation of the system is performed. The re- sult shows that the data of receiver remains the character of the transmitter' s.
