In this paper, the authors present one-way and two-way Ultra WideBand (UWB) relay systems using a multiple-antenna relay with antenna selection and that using single-antenna relay selection. In particular, Amplify-and-Forward (AF) and DeTect-and-Forward (DTF) relaying schemes are considered for these systems. The exact formulae for the end-to-end Signal-to-Noise Ratio (SNR) outage probabilities of the one-way AF and one-way DTF relay systems are derived. In order to minimize these outage probabilities, the optimal power allocation strategies are presented.
