Poly Phase Zero-Correlation Zone Sequences based on Complete Complementary Codes and DFT matrix

Abstract

Recently, numerous constructions of zero correlation zone (ZCZ) sequences have been introduced e.g. based on perfect sequences and complete complementary codes etc.. However, the previous construction method which based on complete complementary code is lacking for merit figures when none of whose elements are zero. In this paper, a new construction method of ZCZ sequences based on complete complementary codes is proposed. By proposed method, the poly phase ZCZ sequences with greater than 1/2 merit figure are constructable.
