Abstract

A new spread spectrum communication system utilizing chaotic frequency modulation of sinusoidal signals is discussed. A single phase lock loop (PLL) system in the receiver is used both to synchronize the local chaotic oscillator and to recover the information signal. We study the dynamics of the synchronization process, stability of the PLL system, and evaluate the bit-error-rate performance of this chaos-based communication system.

摘要

本文讨论了一种利用正弦信号的混沌频率调制的新型扩频通信系统。接收机中的单相锁相环（PLL）系统既用于同步本地混沌振荡器，又用于恢复信息信号。我们研究了同步过程的动力学、PLL系统的稳定性，并评估了这种基于混沌的通信系统的误码率性能。
