Applying Time-Reversal Technique for MU MIMO UWB Communication Systems

1 Abstract—Time Reversal (TR) is a technique to focus broadband signals tightly in time and space. Previously, this technique has been used in acoustics, medical and especially in underwater communication applications. It is capable of reducing noises, such as: Inter-Symbol Interference (ISI), InterUser Interference (IUI). . . , while the used equipments are more simple than complex Equalizers at the transmitter and receiver . TR technique is combined with Ultra Wideband (UWB) to offer a new solution for reducing the cost and complexity of UWB receiver. In this paper, we focus on presenting the operational mechanism of TR technique and giving some specific results which concern with applying TR technique for UWB system.
