SEMA系统的误码性能分析
摘要
介绍了一种新型的扩频多址系统。由于独特的扩频方式
该系统具有很强的保密性。本文通过概率分析
着重对这种系统的多址干扰、自干扰特性进行了研究并给出了误码率的数值结果。
Abstract
A novel kind of spread spectrum system is introduced. The enhanced transmission security arises from the special spectrum spreading and de-spreading processes. By statistical analyzing
the characters of the MAI and self-interference are studied and the numerical results of the error bit rate are given.
