摘要
为了保证对伪随机序列进行宽间隔处理后序列仍有最佳性能值,对基于混沌的跳频序列分别采用圆环频带法和对偶频带法进行宽间隔处理,并对经这两种方法处理所得到的宽间隔跳频序列的平均跳频间隔、相关性、平衡性进行分析和比较,仿真分析表明采用对偶频带法构造的宽间隔跳频序列更有利于抗多径衰落,而在含奇数个跳频点的多用户跳频组网中采用圆环频带法构造宽间隔跳频序则具有更强的抗干扰性能。
In order to get optimal FH sequences with given minimum gap,the chaos-based FH sequences are processed by circle band and symmetry band,then the average of gap,balance and correlation property of the two processed FH sequences with given minimum gap are analyzed and compared.The simulation analysis indicates that the chaotic FH sequence with given minimum gap constructed by symmetry band is more advantageous to anti-multi-path fading while the circle band could improve the anti-jamming performance of multi-user FH system with odd frequency points.
