Diversity Combining for the Z-Channel
Torleiv Kløve, Paul Oprisan, B. Bose · IEEE Transactions on Information Theory · 2005
Corrupted packets that cause retransmission requests in automatic retransmission request (ARQ) systems can be reused. They can be combined with additional stored copies of the transmitted packet in order to obtain a single packet which is more reliable than any of the constituents. A scheme which suits the Z-channel is proposed here and the performance is analyzed under different coding assumptions.
