[Industry research] 07304388 DL : 1: We present a novel beamforming technique for multi-user indoor wireless communications called regularized time-reversal (RTR). A comparison with other time-reversal techniques is provided with respect to bit error rate and spatial focusing performance in mm-wave massive MIMO systems. We verify that the proposed technique can be used for space-division multiple access in such scenarios.

[Industry research] 07355304 DL : 0: We present a novel beamforming technique for multi-user frequency-selective indoor channels called interference-nulling time-reversal (INTR). The beamformer is implemented with a pre-filter designed to minimize the interuser interference present in conventional time-reversal (TR). Moreover, our technique relies on a large number of antennas at the transmitter to mitigate inter-symbol interference, enabling low computational complexity receivers. We demonstrate that INTR outperforms previous TR techniques with respect to average bit error rate per user and achievable sum rate. Thus, INTR can be used for space division multiple access in no-Iine-ofsight mm-wave massive MIMO, providing remarkable diversity and multiplexing gains.
