摘要
采用改进型Logistic映射迭代产生的混沌序列,提出混沌超宽带(UWB)多用户通信系统模型;并针对该系统混沌跳时脉冲位置调制下的性能进行分析,重点仿真了不同用户数、不同跳时序列下的误码率性能;由分析和仿真知,系统性能得到了改善,抗干扰能力增强。
In this paper,the chaotic sequences are created by iteration methods based on advanced Logistic-map,and then they are applied in multiuser UWB system,the performance of the system on chaotic time-hopping PPM is analyzed.The BER（Bit Error Rate）performance of multiuser UWB system under different users and different time-hopping sequence are discusses intensively,the result indicate that the chaotic sequence can improve the performance of system and enhance the capability of anti-jamming.
