Abstract

Time reversal (TR) is a technique that can achieve remarkable temporal focusing (delay spread reduction) and spatial focusing in the context of wideband multipath propagation channels. In this paper, based on wideband measurements in reverberation chamber (RC) channel, we predict the characteristics of TR on the temporal compression and the spatial focusing. For the first time, we have analyzed the effects of the signal bandwidth on the temporal focusing and spatial focusing. Furthermore, the influence of the lower frequency band of the signal on the special focusing is demonstrated.
