Abstract:
1. In a communication system comprising one or more first transceiving communication devices and two or more second transceiving communication devices that are configured to coordinate transmission of the same information signals, a method of combining signals respectively transmitted from the one or more first transceiving communication devices, comprising: (a) estimating at each of the two or more second transceiving communication devices, a time domain channel response for a radio frequency channel from the one or more first transceiving communication devices to each of the two or more second transceiving communication devices based on receiving known signals transmitted from the one or more first transceiving communication devices; (b) generating at each of the two or more second transceiving communication devices, a time-reversed channel response from each time domain channel response; (c) convolving at each of the two or more second transceiving communication devices, a corresponding time-reversed channel response with an information signal to produce convolved information signals; and (d) summing and transmitting at each of the two or more second transceiving communication devices, the convolved information signals intended for the one or more first transceiving communication devices.
