On the Performance of MU SIMO/MIMO UWB Communication Systems Applying Time-Reversal Technique

Time Reversal (TR) is a technique to focus broadband signals tightly in time and space domains. Previously, this technique has been used in acoustics, medical and especially in underwater communication applications. TR technique is combined with Ultra Wideband (UWB) technology to offer a new efficient solution for the cost and complexity degradation of UWB receivers. It is capable of interference reduction such as: inter-symbol interference (ISI), inter-user interference (IUI)…, meanwhile the user equipments have no need of complex equalizers at the transmitter and receiver. In this book chapter, we focus on presenting the operational mechanism and giving some specific results which concern with applying TR technique for UWB communication systems. Specifically, the channel capacity is investigated in SIMO and MIMO UWB systems.
