New families of asymmetric zero-correlation zone sequence sets based on interleaved perfect sequence

Families of asymmetric sequence pair set with zero‐correlation zone via interleaved technique

“…In recent years, the designs of ZCZ sequence set and ZCZ sequence pair set have been researched based on interleaved technique and perfect sequence or sequence pair [4][5][6][7][8][9][10]. Recently, the ZCZ sequence set that was composed of multiple sequence subsets, which also is said as asymmetric ZCZ (A-ZCZ) sequence set, has been proposed and obtained [11][12][13][14][15][16][17][18]. Tang et al [11] presented several types of binary A-ZCZ sequence set and Hayashi et al [12,13] constructed several types of binary and ternary A-ZCZ sequence set.…”

“…In addition, Zhang et al [14] got complementary A-ZCZ sequence set and Li et al [19], Feng et al [20] proposed inter-group complementary codes. Moreover, Torii et al [15], Wang et al [17] designed several types of polyphase A-ZCZ sequence sets.…”

A Novel Class of Structured Zero-Correlation Zone Sequence Sets

“…A.2171 correlation function of sequences of the same subset (intrasubset correlation function). There exist several sequence sets having similar subset and inter-subset correlation functions, which are wider than intra-subset correlation functions [13], [16], [18]- [21], [26], [35], [43], [44], [47], [48], [52], [55]- [58], [61]. We have proposed a class of ternary sequence sets for both periodic and aperiodic correlation functions whose sequence sets can work with both even and odd correlations for spectrum spreading communications.…”
