Abstract

Orthogonal codes are integral part of DS-CDMA based communication systems. Walsh Hadamard orthogonal codes are extensively employed in present day CDMA systems. In this paper, Orthogonal Gold codes are presented as a possible option for spreading sequences in Quasi-Synchronous CDMA (QS-CDMA). These codes are compared with Walsh Hadamard codes in terms of individual user performances and average BER performance. It is observed that codewords from Orthogonal Gold set perform more uniformly compared to individual codewords of Walsh Hadamard set and also give comparable average BER performance.
