Abstract

In this paper we focus on enhanced design issues of synchronous direct-sequence spread-spectrum networks. The overall figure in a DS/CDMA-network is the capacity for a certain link quality. To enhance the capacity means to reduce the multi-user interference. The presented multi-user detection scheme is simple to implement in digital receiver structures. The investigations are done on the basis of simulations. The results are presented in graphs. All investigations are compared to other well known schemes
