摘　　要：本文提出并分析了一种在对混沌映射区间进行二级划分的基础上采用旋轮策略动态量化的混沌宽间隔跳频序列生成方案。新方案可有效增加混沌跳频序列的抗相空间重构攻击的能力。本文进一步通过数值模拟与统计分析对新方案与多值量化混沌宽间隔跳频序列生成方案进行了比较,结果表明:该方法速度快,生成的跳频序列具有优良的多址性能。In this paper a generation method of frequency hopping sequences with given minimum gap based on chaos is proposed to address the problem of phase space reconstruction attack.This method is based on the technique of twice interval-division and rotated wheel dynamic quantification.Analyzed by computer simulation and statistics,the paper compares the performance of the proposed scheme with the existing multi-values quantization methods for the generation of chaotic FH sequences with given minimum gap.Results show that the proposed method is capable of obtaining quicker generation speed and better multi-address performance than the other methods,hence it is suitable for the FH-CDMA communication systems.
