Abstract:
1. A method of transmitting data from a first radio frequency communication system to a second radio frequency communication system, the method comprising steps of: receiving by a plurality of antennas of the first radio frequency communication system waveforms that resulted from sounding environment using one or more channel sounding bursts transmitted from the second radio frequency communication system, the waveforms comprising reflections of the one or more channel sounding bursts from one or more scatterers; processing the waveforms using time-reversal and Singular Value Decomposition to (1) select a first selected scatterer from the one or more scatterers, and (2) determine first signatures for launching from the plurality of antennas a first transmission temporally and spatially focused on the first selected scatterer, each first signature corresponding to a different antenna of the plurality of antennas; convolving first data with said each first signature to obtain first transmission waveforms, a first transmission waveform per antenna of the plurality of antennas; and transmitting the first transmission waveforms from the antennas of the plurality of antennas, each first transmission waveform transmitted through the antenna corresponding to said each first transmission waveform, so that the first data is temporally and spatially focused on the first selected scatterer.
