The set of complementary sequences with multi-width zero cross-correlation zone (ZCCZ) can obtain multiple different zero correlation zone (ZCZ) widths between different sequence groups comprising the sequence set, which ensures a wider usage of such multi-width ZCCZ complementary (MWZC) sequences. This paper further discusses the properties of three zero correlation zone (T-ZCZ) of MWZC sequences. Based on the discussion, we provide the applications of MWZC sequences in multi-carrier code division multiple access (CDMA) communications, namely MWZC-CDMA system. Compared with traditional CDMA systems using sequences with single-width ZCZ, the proposed MWZC-CDMA system can obtain more flexible choices when the number of users increases and the access position changes.
