Description
Summary:A highly reliable transmission scheme based on a combined application of network coding and superposition modulation is introduced for a non- relay wireless communication system. It is shown that by employing superposition modulation, the side information needed for error recovery can be transmitted over the same set of resources as the original packets. A sub-constellation alignment mechanism for constructive combining of the least significant bits of the received symbols is proposed for efficient side information dissemination. The outage analysis and numerical results show that the proposed system can offer significant gains in link reliability.
