On the Performance of the Time Reversal SM-MIMO-UWB System on Correlated Channels

Abstract EN

The impact of spatial correlation on the multi-input multi-output ultrawide band (MIMO-UWB) system using the time reversal (TR) technique is investigated.

Thanks to TR, several data streams can be transmitted by using only one antenna in a system named virtual MIMO-TRUWB.

Since the virtual MIMO-TR-UWB system is not affected by the transmit correlation, under the condition of the high spatial correlation, it outperforms the true MIMO-UWB system with multiple transmit antennas.

The channel measurements are performed in short-range indoor environment, both line-of-sight and non-line-of-sight to verify the adopted correlated channel model.
