On the use of Time Reversal for digital communications with non-impulsive waveforms

This article analyzes a comparison of a generic digital communication and a Time Reversal communication systems. The principles and properties of Time Reversal are presented for non-impulsive waveforms. The metrics used to characterize time focusing and the measures used for the simulations are outlined. These measures are used to illustrate how the proposed metrics vary as a function of the bandwidth of the signal and the bandwidth of the channel. Bit Error Rate performances are finally presented to corroborate the results of the studies.
