Abstract :
A generalized chirp-like (GCL) sequence is constructed by modulating a Zadoff-Chu sequence with a unimodular sequence. Under some specific conditions, the magnitude of the cross-correlation between GCL sequences is known to be the same as that of the corresponding Zadoff-Chu sequences. In this paper, we further investigate the conditions under which such a relation holds. Using them, we construct a new class of optimal zero-correlation zone (ZCZ) sequences.
