Abstract
A receiver device includes circuitry to measure an error vector of a pulse amplitude modulation (PAM) sequence in a signal received from a transmitter and control logic coupled to the circuitry. The control logic removes estimated linear components from the measured error vector to generate a non-linear error vector. The control logic further determines, with reference to a set of lookup table (LUT) values, one or more tuning parameters for the PAM sequence based on the non-linear error vector and modifies the set of LUT values according to the one or more tuning parameters. The control logic further provides the modified set of LUT values to the transmitter, which when used by the transmitter to add digital pre-distortion to the PAM sequence, causes the non-linear error to be at least partially removed from the signal.
