Summary:
This paper proposes a prefiltering-based transmission scheme for pulsed UWB system by shifting the signal processing needs from the receiver at the mobile unit to the transmitter at the basestation where power and computational resources are plentiful. We exploit antenna array in the basestation transmitter and take advantage of the spatial and temporal diversities to mitigate the MUI of a TH multiple access UWB communication system. The prefiltering scheme is developed to meet the zero-forcing (ZF) criterion. A simple correlation receiver is proposed at the mobile unit to combine the desired signal stemmed from all the transmitting antennas. The performances under different scenarios are extensively evaluated over multiple-input single-output (MISO) channels.
