一种生成宽间隔跳频序列的改进对偶频带法
|
摘要
对偶频带法在构造宽间隔跳频序列时存在频点间距范围的限制和遗漏满足宽间隔的频率对的问题。针对这两个问题,为了进一步提高对偶频带法的抗干扰性能,提出了一种改进的对偶频带法的宽间隔处理方法。利用Matlab软件对算法进行了实例仿真,计算并对比了两种方法实例的汉明相关值。实验结果表明,改进对偶频带法简化了宽间隔跳频序列生成结构,汉明相关性能优于对偶频带法。
Dual sub-band method is used to construct wide-gap frequency-hopping(FH) sequence with the limitation of frequency point spacing and omission to satisfy the frequency of wide interval.For the two problems,an improved method of wide interval processing for dual sub-band method is proposed to further improve the anti-interference performance of dual sub-band method.Matlab software is used to simulate the algorithm,and the Hamming correlation values of two methods are calculated and compared.The experimental results show that the improved dual sub-band method simplifies the generation structure of the wide-gap FH sequence,and the Hamming correlation performance is better than that of the dual sub-band method.
