Abstract :
In this paper, the theory of perfect punctured ZCZ sequence pair sets is defined. The methods for constructing perfect punctured ZCZ sequence pair sets are based on the perfect punctured binary sequence pair and some matrices. A new frame, used in QS-CDMA or S-CDMA system which requires good periodic correlation functions of spectrum frequency codes, is presented and proved. The performance of perfect punctured ZCZ sequence pair sets in S-CDMA and QS-CDMA system is analyzed with MATLAB tool. Compared with Gold code, perfect punctured ZCZ sequence pair sets have a longer zero-correlation zone, and are suitable for S-CDMA and QS-CDMA system
