摘要/Abstract

摘要： 在对已有混沌序列构建方法研究的基础上,用状态转移图分析了基于Logistic构建跳频序列的局限性,并利用随机过程的相关理论,提出了基于方阵重构法的优化方案。该方案在跳频性能指标方面达到或优于原有方案,在硬件实现时降低了乘法次数,减少了硬件资源的占用量,增加了跳频序列的可实现性。

Abstract: The current research on the generation of frequency hopping(FH) sequences based on chaotic map is investigated.And then,the limitation of FH sequences generation based on Logistic is analyzed by use of state shift map.Furthermore,an improved scheme of FH sequences based on phalanx is proposed by using the related theory of random process.It has been proved that the FH performance of the scheme is equal to or even better than the primary scheme.More over,the multiply times of the redesigned method can be reduced in hardware realization with decreased occupation of hardware resources,and the implement probability of FH sequences can be increased.
