摘要
针对周期抽取法构造的混沌跳频序列在均衡性方面缺陷,提出了利用周期抽取与多比特抽取结合法产生迭代式TOD混沌跳频序列,理论分析及仿真结果表明,该方法构造的贝努利随机序列,具有很好的均衡性、动态特性、汉明相关性等性能,相对于多值量化与比特抽取相结合法减少了运算量,便于增加跳频序列的复杂度。
In order to avoid the deficiency of the periodic extraction algorithm in the balance, an improved algorithm combining the periodic extraction and reshaping operation is proposed to generate the iterative T0D Chaotic FH Sequences. The theoretical analysis and simulation show that the Bernoulli random sequences which are generated by this method have good properties in balance, dynamic trait and Hamming correlation. Comparing the algorithm of quantization function and reshaping operation, the method has low computational complexity, and increases the complexity of FH Sequences.
