A method and system reduces data error in an automatic repeat request (ARQ) communications system. Data is code-combined in a communications session that uses an automatic repeat request protocol by sending alternate phases of an encoder state. The underlying signaling constellation is changed when code-combining performance degrades. An optimal signaling constellation and code rate can be determined from a previous packet acknowledgment (ACK) status or from a look-up table previously determined by use.
