A Complementary Quadriphase Jacket Sequence Design for DS-CDMA System

A class of complementary quadriphase sequence based on Jacket matrix was proposed in this paper. It is with zero cross correlation zone and near optimal autocorrelation to efficiently eliminate the interuser interferences for DS-CDMA mobile communication systems. Unlike the conventional designs, the proposed sequences can be easily extended and generated to large odd and even sizes by using a fast linear Hadamard transform. The computer simulations also show that the proposed sequences have better performance than conventional multiuser spreading CDMA systems.
