The theoretical limits of asynchronous DS-CDMA systems over AWGN channles are investigated by computing the statistics of the associated Shannon capacity. A comparison is reported between chaos-based spreading and ideal random spreading Gold codes and maximum-lenght codes. It is shown that chaos-based spreading results in a nonnegligible increase of the capacity.

Abstract

The theoretical limits of asynchronous DS-CDMA systems over AWGN channles are investigated by computing the statistics of the associated Shannon capacity. A comparison is reported between chaos-based spreading and ideal random spreading Gold codes and maximum-lenght codes. It is shown that chaos-based spreading results in a nonnegligible increase of the capacity.
