Abstract
In this paper, we suggest the novel MIMO-UWB transceiver structure which can easily be adapted for various MIMO schemes and presents MIMO channel model for obtaining correlation characteristics among channels to analyze the performance. From the indoor channel modeling, we obtain the interferences among antennas due to the MIMO channel formation through numerical simulation and analyze the performance of MIMO-UWB system under frequency selective fading. Especially, to reduce the excessive computational complexity due to the inverse matrix computation of channel transfer function, we take the scheme combining the transmitting signals estimated from each receiving antenna after recovering each transmitting antenna signal from a receiving antenna.
