Claim Text:
1. A system comprising: a first transceiver and a second transceiver being configured to sense a respective signal strength for individual ones of a plurality of frequencies of an OFDM wireless channel; the first transceiver and the second transceiver being configured to determine whether the individual ones of the plurality of frequencies meet a threshold signal strength based at least in part on the respective signal strength; the first transceiver being further configured initiate a transmission of a data signal comprising a plurality of artificial data corresponding to the plurality of frequencies failing to meet the threshold; and the second transceiver being further configured to determine whether individual ones of the plurality of frequencies meet the threshold and receive a plurality of genuine data from the data signal by multiplying a plurality of subcarriers in the data signal by a channel gain corresponding to one of the plurality of frequencies determined to meet the threshold.
