In an embodiment, a method includes: providing a first set of coefficients to a digital pre-distortion (DPD) corrector, the DPD corrector receiving a input signal having a first profile, the first set of coefficients being associated with the first profile; in response to detecting a change in a profile of the input signal from the first profile to a second profile, extracting, in response to an output signal converging to the input signal, a second set of coefficients corresponding to the second profile, the output signal being based on an output of the DPD corrector; and generating a third set of coefficients based on the first and second sets of coefficients, the third set being different from the first and second sets.
