Abstract

The use of chaotic spreading sequences is a new approach for DS-CDMA systems. Some chaotic PN spreading sequences show better correlation properties than conventional binary PN sequences, which are crucial for the BER performances. This paper is presenting a selection criterion for optimal sets of PN chaotic sequences, which are generated from periodic orbits of a particular class of chaotic dynamics. Finally, their BER performances in a synchronous DS-CDMA system are compared for two particular cases to show the superiority of chaotic sequences.

周期混沌扩频序列具有比常规序列更好的相关特性-误码率分析

利用混沌扩频序列是DS-CDMA系统的一种新方法。一些混沌PN扩展序列表现出比传统二进制PN序列更好的相关特性，这是提高误码率的关键。本文给出了一类特定混沌动力学的周期轨道生成的PN混沌序列最优集的选择准则。最后，比较了两种混沌序列在同步DS-CDMA系统中的误码率性能，证明了混沌序列的优越性。
