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 ensure the optimal performance of the sequence after the wide-interval processing, the chaos-based hopping sequences are respectively processed by the wideband method using the circular band method and the dual band method, and by the two methods, The average frequency hopping interval, correlation and balance of the wide interval frequency hopping sequence are analyzed and compared. The simulation results show that the wide frequency hopping sequence constructed by the dual frequency band method is more advantageous to anti-multipath fading. However, Frequency hopping multi-user network using frequency hopping ring method to construct a wide frequency hopping sequence has a stronger anti-jamming performance.
