Abstract :
Sequences with desirable correlation properties have wide applications in today´s communication systems. In this paper, we first extend the known results on zero autocorrelation zone of Golay sequences to 4q-QAM Golay sequences and show three constructions of 4q-QAM Golay sequences with a large zero periodic autocorrelation zone, where q ≥ 2 is an arbitrary integer. We then determine the Golay pairs which have large zero periodic crosscorrelation zone.
