Abstract
At a transmitter of a communication system, a target signal and a primary coded signal are produced in response to an input signal. The primary coded signal is intended to match the target signal. Also produced is encoded enhancement information indicative of how closely the primary coded signal matches the target signal. At a receiver, the primary coded signal is reconstructed, the encoded enhancement information is decoded, and an enhanced reconstructed signal is produced by applying the decoded enhancement information to the reconstructed primary coded signal.
