System model. Block diagram of the baseband communication link. Two scenarios are shown by the dashed boxes, based on the source of distortion: (top) distortion due to imperfect compensation of a nonlinear amplifier and (bottom) phase noise at the receiver. These distortions are compensated with a demapper based on the mean and covariance the received symbols
