The present invention relates to a method and apparatus in a digital communication system that employs phase-aided adaptive modulation to overcome phase noise impairments. The transceiver is configured to transmit a message comprising channel symbols from a primary and a secondary set of channel symbols, wherein the primary set of channel symbols comprises channel symbols having different phase with respect to one another and the secondary set of channel symbols comprises only channel symbols with a fixed known phase.
