Summary:
An asymmetric zero correlation zone (AZCZ) sequence set is a type of ZCZ sequence set and consists of multiple sequence subsets. It is the most important property that is the crosscorrelation function between arbitrary sequences belonging to different sequence subsets has quite a large zerocrosscorrelation zone (ZCCZ). Our proposed AZCZ sequence sets can be constructed based on interleaved technique and orthogonalitypreserving transformation by any perfect sequence of length P=Nq(2k+1) and Hadamard matrices of order T≥2, where N≥1, q≥1 and k≥1. If q=1, the novel sequence set is optimal ZCZ sequence set, which has parameters (TP,TN,2k+1) for all positive integers P=N(2k+1). The proposed AZCZ sequence sets have much larger ZCCZ, which are expected to be useful for designing spreading sequences for QSCDMA systems.
