Abstract

Time Reversal is well-known in Impulse Radio Ultra Wideband communications (IR-UWB) for its ability to improve performance and complexity both in noise limited scenarios and multiuser interference (MUI) limited ones. In an ad-hoc uncoordinated network, where no power control is possible, no users’ channels are known, or no elaborate multiple access techniques can be deployed, Time Reversal is imperfect. In this paper, a comparative analysis between conventional Rake schemes and Time Reversal ones is made in order to evaluate robustness towards the absence of the mentioned operations.
