Chaotic spread spectrum-based model design and simulation of multi-user emergency communication system

Abstract

In view of the present issue that channel noise seriously affects the communication quality of emergency communications,this paper studied the channel noise source and essential characteristics of emergency communication system and proposed a channel model of emergency communication,discussed the principles of interference noise suppression in chaotic spread-spectrum emergency communication system,designed a multi-user simulation model of chaotic spread spectrum emergency communications system,and advanced its Bit Error Ratio(BER) simulation and analysis in typical channel interference noise.The simulation results show that the chaotic spread spectrum communication system can effectively suppress strong noise interference and improve system BER performance in emergency communications significantly.
