Abstract

This paper proposes that the Hopfield neural network (HNN) with hyperbolic tangent activation is introduced and applied to multiuser detection in direct sequence-ultra-wideband (DS-UWB) systems. It can approximate to maximum likelihood (ML) detector by mathematical analysis. The HNN with hyperbolic tangent activation (tanhHNN) can enhance the performance of HNN detector. According to the HNN technology, the computer simulation results show that they have good performances and much lower computational complexity in a multiuser environment.
