Abstract

This paper investigates the different sequences that can be used in direct sequence division multiple access (DS- CDMA) systems. The auto-correlation, cross correlation, the mean square correlation measurements ( RAC, RcC ) and merit factor (MF) are used for evaluating the performance of different spreading sequences. The results obtained small set of Kasami sequences is the most effective of binary sequences families in terms of correlation measure, but this set suffers from the limited number of sequences. Overall among orthogonal category, Orthogonal Gold sequences and Golay complementary sequences are a better candidate in synchronous CDMA applications.
