一种宽间隔混沌跳频序列快速生成方法
Method for fast generating wide-gap chaotic frequency hopping sequences
摘要
Abstract
Aiming at the problem of poor real-time performance caused by the bit extraction method during the process of creating chaotic frequency hopping (FH) sequences,a new generation algorithm for chaotic FH sequences based on segmented iterative is proposed.The chaos mapping tracking real-value point obtained by segmented iterative is expressed as a binary decimal,and the wide interval sequence is generated by using the methods such as periodic multi-bit overlapping extraction,nonlinear matrix transformation and improved random shift replace algorithm.The simulation result shows that,under the premise that the balance properties,hamming correlation,FH interval,anti-prediction capacities and other FH sequence performances are not lower than the existing algorithms,the average number of iterations can be reduced by about 45％,and it also has the advantage on the aspects of real-time,storage footprint and the extended sequence period.Through verification,this algorithm is suitable for the wireless FH communication system that requests the flexible replacement of FH patterns.关键词
