Construction of mutually orthogonal Z-periodic complementary sequences

Based on the interleaving between a coefficient matrix and a traditional zero correlation zone sequence set, a novel construction method of Z-periodic complementary (ZPC) sequences is presented. The constructed ZPC sequence set consists of multiple ZPC sequence groups. Each sequence group can be considered as a traditional ZPC sequence set and different ZPC sequence groups are orthogonal each other. As a result, the proposed mutually orthogonal ZPC (MOZPC) sequence groups can be really seen as an extension of traditional ZPC sequence set and can support a larger number of users.
