Abstract

We employed photonic radio frequency (RF) arbitrary waveform generation to demonstrate space–time compression of ultrabroadband wireless signals through highly scattering multipath channels. To the best of our knowledge, this is the first experimental report that explores an RF-photonic transmitter to both characterize channel dispersions in real wireless environments and generate predistorted waveforms to achieve focusing through the multipath channels. Our experiments span a three octave frequency range of 2–18 GHz, nearly an order of magnitude beyond the 2GHz instantaneous bandwidth reported in previous spatiotemporal focusing experiments relying on electronic waveform generators.
