Abstract

This paper provides a novel performance formulation for UWB systems that successfully captures the unique multipath-rich property and random-clustering phenomenon of UWB channels. Using the Saleh-Valenzuela model, we are able to characterize the pairwise error probability (PEP) performance for UWB systems employing multiband OFDM based on cluster arrival rate, ray arrival rate within a cluster, and cluster and ray decay factors. In addition, a PEP approximation technique is established, which allows us to obtain a closed-form PEP formulation that provides insightful understanding of the effect of channel characteristics on the performances of UWB systems. Finally, simulation results are provided to support the theoretical analysis.
