For adaptive packet retransmission control, network coding (NC)-based schemes have been proposed to reduce the number of packet retransmissions. However, the NC-based schemes have two fundamental drawbacks; the need for a counterpart packet of member packets and an overhearing packet management method. To mitigate these problems, we propose a novel superposition modulation (SM)-based scheme based on cross-layer design. However, when the SM technique is introduced into the system, the bit error probability increases. Therefore, to decrease the bit error probability, we utilize the soft combining (SC) technique. The effectiveness of our scheme is demonstrated through computer simulations.
