Abstract :
In this paper, we study the outage behavior of a relay-based communication channel for time hopping ultrawideband (TH UWB) systems. Specifically, we analyze the outage probability and ε-outage capacity in single relay network scenarios, and outage probability in multiple relays network scenarios. Our results show that increasing transmission power is not an efficient way to improve outage probability due to the effect of multi-user interference at relays and the destination. The accuracy of the proposed analytical outage probability models is verified through simulations.
