Abstract: To lower the complexity of the existing methods, a new sequence design method of zero correlation zone (ZCZ) based on interleaved technique was proposed. For a given ZCZ sequence set where the length isL, the size of the sequence isM, and the zero zone isz, a new sequence set is obtained bymtimes ofrecursive constructionsusing interleaved technique. The length andwidth of the new sequence set is 2mtimes as large as those of the original one, and the size of the sequences remains the same asM. The new ZCZ sequences are easily implemented in terms of hardware and software, and is suitable for the approximately synchronous CDMA (AS-CDMA) communication system.
