Performance of ultrawideband cooperative relay systems in the presence of narrowband interference

Abstract

In this paper, the performance of ultrawideband (UWB) cooperative relay systems in the presence of narrowband (NB) interference is evaluated for the first time. Specifically, we consider UWB cooperative amplify-and-forward and UWB cooperative detect-and-forward systems where a single-tone NB interferer exists, and present their bit-error-rate analysis. Simulation results based on such analysis demonstrate how the NB interference impacts on the system performance.
