Abstract
In this paper, we propose to improve the performance of impulse-radio ultra-wideband (IR-UWB) systems by means of cooperative relaying. With regard to a simple practical realization, we focus on a non-coherent system setup in conjunction with amplify-and-forward (A&F) relaying. In particular, considering a two-hop scenario we propose to employ a double-differential encoding scheme at the source node and single differential decoding at the relay and the destination node, respectively, so as to efficiently limit intersymbol-interference (ISI) effects. A thorough performance analysis of the proposed scheme is provided, along with a closed-form optimization of the transmit power allocation between source and relay. Simulation results illustrate the excellent performance of the proposed scheme, which is compared to alternative coherent and noncoherent schemes based on A&F relaying and decode-andforward (D&F) relaying. © 2010 IEEE.
