Abstract A construction scheme of sequences with good properties for multi-carrier code division multiple access communication systems is presented. The proposed method is based on sequences with Zero Correlation Zone (ZCZ), and a novel kind of sequences with complementary mode and multiple subsets can be obtained by interleaving these ZCZ sequences. The designed sequences have periodic complementary characteristics, which leads to stronger ability to resist multi-path interference and multiple access interference. This paper proves the periodic correlation properties of the constructed sequences, and the construction example shows that the proposed method combines effectively complementary characteristics and ZCZ characteristics.
