| 摘 要： | 提出用一种简单的分段线性映射 ,构造混沌跳频序列 ,以取代跳频通信中的伪随机序列 (PN序列 )。分析了此混沌序列的相关特性 ,并与Logistic混沌序列进行了比较。仿真和实验结果表明 ,此序列具有较理想的相关特性 ,应用于跳频通信中可获得较好的抗干扰能力。

| Abstract: | This paper proposes to substitute pseudo noise (PN) sequence in a frequency hopping(FH) communication system with a simple piecewise linear mapping chaotic sequence, and analyses the correlation property of the sequence. Simulation and experiment results show that this sequence has a fairly ideal correlation property. Good antijamming ability can be gained by using this sequence in FH communication. |
