Construction of ZCZ periodic complementary sequence set with flexible subsequences

Abstract

Based on orthogonal matrices,a construction of zero-correlation zone (ZCZ) periodic complementary sequence sets are proposed.The resultant ZCZ periodic complementary sets have flexible number of subsequences.Moreover,the ZCZ periodic complementary sequence sets are optimal.ZCZ periodic complementary sequence sets with flexible subsequences are more useful in communication systems.
