Summary:
Sequence set with Three Zero Correlation Zones (TZCZ) can efficiently mitigate the Multiple Access Interference (MAI) and Inter Symbol Interference (ISI) caused by multipath in CDMA system. In this paper, an algorithm for generating TZCZ sequence set is presented. Moreover, in order to study the restrictions among the parameters such as the length of the sequence, the number of the sequences and the length of the TZCZ etc., the corresponding theoretical bound is investigated and proved. Additionally, the performance of TZCZ sequence in MCCDMA system is evaluated to confirm the capability of interference cancellation as well as system capacity improvement.
