A system and method for demodulating a data packet in an automatic repeat request communication system is disclosed. Specifically, in a communication system that combines the energy of an initially transmitted data packet with the energy of a retransmitted version of the data packet, the inventive system and method measures the "usability" of the initially transmitted data packet that fails an error-checking procedure and the "usability" of a retransmitted version of the data packet. If the initially transmitted version and the retransmitted version of the data packet are both "usable", the energies of the data packets are combined. The combined data packet is then subjected to the error-checking procedure. If the combined data packet fails the error-checking procedure, the energy of either the combined packet or the retransmitted packet is stored for later combination with a subsequently-retransmitted version of the data packet.
