ABSTRACT:

We study the effect of noise on the quality of communication in a multiple-in-single-out (MISO) communications system based on time-reversal (TR). We look at two situations, first ambient noise surrounding the source/receiver, then instrument noise at the transmitter array; the measures of merit are the inter-symbol interference (ISI) and the bit-error-rate.

Further, we discuss how the focusing of broad-band signals in a TR-based communications system can be leveraged to deliver coherent power to a spatially localized region. With numerical simulations, we investigate the potential use of this time-reversal system in broadband wireless communication systems.
