摘要
提出了基于混沌跳时(CTH)多址的BPSK超宽带系统,讨论了该系统的工作原理,从理论上分析了系统的多址干扰,通过仿真说明了如何选取系统参数降低系统的误码率,提高系统性能.同时该系统具有低截获率和高保密性等优点,具有较高的使用价值.
A BPSK UWB system using chaotic time-hopping code is put forward. Analyzing the system＇s principle, this paper emphasizes on discussing multiple-access interference （MAD of the system and on explaining how to choose the system parameters in order to reduce BER and improve the performance of the system though simulation. Furthermore the system has many advantages such as low probability of detection and high security.
