Abstract :
In this paper, the theory of ZCZ sequence pairs set is presented, and a class of ZCZ sequence pairs sets can be constructed based on perfect autocorrelation sequence pair and orthogonal matrix. Based on the system model presented in this paper, and through simulation on MATLAB platform, the performance of ZCZ sequence pairs in S-CDMA, QS-CDMA and A-CDMA system is analyzed. Compared with Gold sequence, ZCZ sequence pairs set has a long zero-correlation zone, and can be used in QS-CDMA system to obtain better system performance with great number of users.
