Abstract

In this paper, we investigate the impact of the transmit spatial correlation on the performance of the spatial multiplexing Multiple-Input Multiple-Output (MIMO) Multi-User (MU) Ultra-WideBand (UWB) system in which a pre-equalizer and a Time Reversal (TR) pre-filter are deployed at the transmitter. The combination of the pre-equalizer and the pre-filter is to mitigate the Multiple-Stream Interference (MSI) and Multiple-User Interference (MUI) caused by transmitting several independent data streams to different users simultaneously and the Inter-Symbol Interference (ISI) while the receivers are kept simple. In order to reduce the complexity of the transmitter, the selective-TR pre-filter is used.
