Abstract

In this paper, interference cancellation (IC) scheme using partial Rake combining is proposed in multiuser ultra-wideband (UWB) fading channels. The UWB system under consideration employs a time-hopping impulse radio multiple access (TH-IRMA) format. Proposed IC scheme includes a design for a modified impulse radio transmitter model, and uses a partial Rake combining technique to estimate the tentative decisions for reconstructing multiple access interference (MAI). In addition, partial user interference cancellation is considered in order to reduce the complexity of receiver. Unlike conventional UWB systems, the proposed IC scheme exhibits little degradation in BER performance as the number of users increases. Moreover, the partial user IC scheme achieves considerable improvement in performance with reduced IC receiver complexity.
