The relative amounts of additive white noise and proportional noise in a communication channel are compensated for by providing adaptive precoding and preemphasis to signal point signals. The amounts of precoding and preemphasis are controlled using scalars to modify the magnitudes of the precoding and preemphasis signals that are combined with the signal point signals. The values of the scalars are transferred between the transmitter and receiver, and the values can be changed without losing synchronization between the transmitter and receiver.
