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 pe

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 pres
