一、引言扩展频谱通信(简称扩频通信)的基本概念是从四十年代末期开始逐步形成的。扩频通信具有较强的抗干扰能力和隐蔽性,并能同时实现多址通信、精确的测距和定时,目前已成为反电子对抗中一种十分重要的手段,越来越受到人们的重视。本文简要地介绍扩频通信技术的基本原理和性能特点,以及系统设计中应考虑的几个问题。最后探讨一下其应用前景。
I. INTRODUCTION The basic concept of spread spectrum communication (abbreviated as spread spectrum communication) is gradually formed from the late 1940s. Spread spectrum communication has a strong anti-interference ability and concealment, and can simultaneously achieve multiple access communication, accurate ranging and timing, has become a counter-electron antagonism in a very important means, more and more people’s attention . This article briefly introduces the basic principles and performance characteristics of spread spectrum communication technology, and several issues that should be considered in system design. Finally, discuss its application prospects.
