Abstract

As the number of users is increased, performance of the conventional DSSS system becomes an issue. Hence, we proposed a novel approach that can provide a significant increase in the number of users in a given bandwidth over that presently available. The proposed technique is based on division of the entire channel into a number of sub-channels having a smaller bandwidth than the entire channel bandwidth. Analytical results were obtained to estimate the number of users when the channel is divided into smaller bandwidth sub-channels. It is seen from the analytical results and computer simulations that the proposed approach allows more users to be accommodated than is now possible with the conventional single carrier DSSS system.
