Abstract :
In this letter, a generic construction of optimal generalized chirp-like ZCZ sequence sets with reduced alphabet size is presented. Further, we can obtain multiple optimal quaternary ZCZ sequence sets with good inter-set cross-correlation property within the zero correlation zone, which outperforms the binary and ternary counterparts.
