Abstract

A class of polyphase signature sequences for direct sequence code division multiple access (DS/CDMA) systems is proposed. The proposed class has zero periodic (=even) crosscorrelation and approximate maximum odd crosscorrelation value N/π, when N is the length of sequences. It is shown that the maximum odd crosscorrelation value of the new sequence has little effect on the performance of the system. The performance of the proposed sequence in DS/CDMA systems is investigated and shown to be better than that of other sequences under asynchronous additive white Gaussian noise channel environment
