Abstract: An apparatus includes an antenna that is configured to transmit a radio frequency signal across a transmission media having a channel response impairment. A transmission path includes an encoder circuit that encodes data on a carrier signal; and a pre-equalizer circuit that is configured to pre-distort the encoded data according to equalizer coefficients representing the channel response impairment. A first equalization path includes circuitry that generates the equalizer coefficients based upon transients resulting from a presence change event for the carrier signal. A second equalization path includes circuitry that generates the equalizer coefficients based upon knowledge of encoded data on the carrier signal. Selection circuitry selects between the first equalization path and the second equalization path.
