| 摘 要： | 混沌现象本身的特点非常适合于充当伪随机码,满足日益增长的通信保密性,安全性要求。提出了一种设计FH-CDMA的新方法,基于logistic映射,利用DSP(数字信号处理器)芯片实现了一种混沌跳频序列,用m序列对数字化混沌系统实施扰动以克服有限精度效应,并对该序列的汉明相关性进行了分析,结果表明它具有良好的性能,适用于实际跳频通信系统。

| Abstract: | Chaotic sequence is quite fit for pseudorandom number because of its characteristics.This paper proposes a novel method to design frequency hopping sequences by using DSP based on Logistic mapping,perturbation of m-sequence is employed to overcome the finite precision effect.It is shown that the sequences have good correlation property. |
