Space-time focusing performance of time-reversal beamforming in rich-scattering indoor channels

We analyze the space-time focusing performance of conventional time-reversal (TR) beamforming in single-user wireless scenarios. We use two indoor wideband channel models to investigate, under uncorrelated scattering, spatial focusing performance of TR increases versus bandwidth and delay spread. We also examine the time focusing performance w.r.t. variations in channel parameters and number of antennas.
