Abstract
An apparatus and method for cancelling and/or attenuating one or more signal impairments included within a transmitted RF signal is disclosed. In at least one exemplary embodiment, a baseband signal is generated based, at least in part, on a predicted impairment signal subtracted from a desired baseband signal. An impairment detection signal may be generated by multiplying the predicted impairment signal by the baseband signal. The predicted impairment signal may be adjusted based, at least in part, on the impairment detection signal.
