Abstract

This paper deals with the optimization of the performance of DS-CDMA system by means of a proper choice of the spreading sequences among those offered by the chaos-based approach. Performance is here linked to the co-channel interference due to the presence of multiple asynchronous users. Optimization is performed considering random trials and looking at the performance achieved in each trial as an instance of a random variable whose average and variance can be combined to give hints on the most promising maps. The analytical results provided by a companion paper allow to select the best candidates among a well characterized family of maps when small spreading factors are considered. The thorough optimization of the sequences produced by these best choices boosts the improvement in communication quality with respect to standard methods from the average 15% to a peak 68%.
