Claim 0:
1. An apparatus of a communication device, the apparatus comprising:
a receiver comprising:
equalization circuitry configured to receive a filtered radio frequency (RF) signal and generate an equalized RF signal;
non-linearity compensation circuitry configured to apply a non-linear feature set to the equalized RF signal to generate a compensated signal, the non-linear feature set including a plurality of weights; and
closed-loop training circuitry configured to:
compare, in a digital domain of the receiver, a plurality of signal constellation points corresponding to the compensated signal with a plurality of training samples to determine an error signal associated with the plurality of signal constellation points, the plurality of training samples generated internally within the receiver; and
adjust the plurality of weights of the non-linear feature set based on the determined error signal.
