We introduce dual-hop ultra-wideband (UWB) relay systems using a multiple-antenna relay with antenna selection and the ones using single-antenna relay selection. In particular, amplify-and-forward (AF) and detect-and-forward (DTF) relaying schemes are considered for these systems. To study and compare the system performance, the exact formulae for the end-to-end signal-to-noise ratio (SNR) outage probabilities of the systems are derived. Numerical results show that the AF and DTF systems using the multiple-antenna relay with antenna selection outperform those using the single-antenna relay selection, respectively.
