基于交织的二元及四元完备序列和序列偶的构造方法

Construction of Binary and Quaternary Perfect Sequences and Sequence Pairs Based on Interleaving Technique

基于交织技术,提出了三类二元及四元完备序列和序列偶的构造方法。分别利用二元完备序列、二元完备互补序列对和二元完备序列偶作为初始序列,通过合理设计带符号移位序列,基于交织获得了不同的二元及四元完备序列和序列偶。这些构造方法均可不断递归地进行,从而获得更多具有新参数的完备序列及完备序列偶。该方法通过引入带符号的移位序列,在一定程度上改善了目标序列的相关性能,为序列的构造提供了新的思路。

Based on interleaving technique,three constructions of binary and quaternary perfect sequences are presented. By relatively employing binary perfect sequence,binary complete complementary sequence mate and binary perfect sequence pair,through properly designing signed shift sequence,various binary and quaternary perfect sequences and sequence pairs are generated based on interleaving. These constructions can be recursively processed to achieve more perfect sequences and perfect sequence pairs with novel pa-rameters. By introducing singed shift sequence, correlation performance of the resultant sequence is im-proved in a certain extent,which offers a new approach of sequence construction.
