Claim Text:
1. A radio frequency (RF) wireless communication system, comprising: a set of wireless transceivers in wireless communications, wherein each wireless transceiver includes: a transmitter that wirelessly transmits a periodic channel monitoring signal to another transceiver within the set of wireless transceivers which responds to the periodic channel monitoring signal by producing a periodic channel impulse response signal; a receiver that receives a periodic channel impulse response signal from the other wireless transceiver; and a control circuit that produces a time-reversal of the received channel impulse response signal, and applies a time-reversal to a signal carrying data to reduce RF signal degradation caused by a communication channel between the wireless transceiver and the other wireless transceiver, wherein the control circuit is configured to: store a previously received channel impulse response signal from the other wireless transceiver; compare the most recently received channel impulse response signal with the stored channel impulse response signal from the other wireless transceiver to determine a difference; and replace the stored channel impulse response signal with the most recently received channel impulse response signal when the difference is greater than a predefined threshold, wherein the control circuit is configured to produce a time-reversal of the received periodic channel impulse response signal from the other wireless transceiver; and transmit the time-reversed periodic channel impulse response signal back to the other wireless transceiver.
