| 摘 要： | 本文给出了基于一类混沌映射的扩频序列产生方法,运用混沌的遍历理论分析了周期趋于无穷时混沌扩频序列的性能,并对实际性能作了计算机模拟。结果显示,混沌扩频序列具有良好的平衡特性、相关特性和理想的线性复杂度,且数量极多,是直接序列扩频通信的优选序列。

| Abstract: | A new spreading sequences generator based on a class of chaotic maps is proposed.
The theoretical performances of such sequences are shown to be good using the ergodic theory of chaos. The practical performances are then found by computer simulation. Results show that the balance property, the correlation property and the linear complexity of chaotic spreading sequences are quite good. Therefore chaotic spreading sequences are good candidates for direct-sequence spread-spectrum communications. |
