HNN-based Multiuser Receiving for Uplink CDMA Systems

In this paper, novel hopfield neural network (HNN) technique is proposed for the multiuser receiving of the uplink CDMA system. The proposed receiving scheme resolves the collective effects of both the inter-symbol interference due to the multipath fading channel and the multiple access interference in the multiuser uplink CDMA communication. Simulations demonstrate the effectiveness of the proposed scheme.
