摘要:Multiple transmit and receive antennas are used MIMO system. The system creates parallel MIMOsubchannels to transmit independent streams of data under the appropriate channel conditions. Similarly,Ultrawideband (UWB) communication has attracted great interest for various applications in recent days.Spatially multiplexed (SM) multiple-input multiple-output (MIMO) systems gains the spectral efficiency aswell as high data rates without consuming additional power, bandwidth or time slots. In this paper, weextend the concept of MIMO to UWB systems. The correlated channel for such purpose is considered andthe performance has been analyzed for spatial multiplexing SM-UWB-MIMO system which is required forestimation. The system performance substantially degrades in the presence of high values of spatialcorrelation. To avoid the degradation of such system, it has been designed for virtual UWB-MIMO TimeReversal (TR) system, so that it is not affected by the transmit correlation. Another novel method to reducethe effect of correlation has been chosen by taking the Eigen value of the channel matrix for thecomputation of the system performance. The result shows its performance.
