Properties of spreading codes constitute a limiting factor on the performance of DS-CDMA systems. In this paper, we investigate the performance of certain sets of Gold codes in a multi-user DS-CDMA system, from a few users to full system load. Simulation results show that as the system load increases, BER graphs of all the codes maintain their steep high-SNR slopes, with no emergence of error floor or significant system saturation. The results indicate that certain sets of Gold codes have good cross-correlation properties that make them resistant to multiple-access interference, making them more suitable for multiple-access applications.
