简介
Network Coded Cooperation (NCC) proved itself worthy to meet the ever increasing demands of the next generation wireless users. In the prevalent relaying schemes, the relay either uses Amplify-and-Forward (AF) or Decode-and-Forward (DF) rigidly over all the signals received. However, some networks use Adaptive Decode-Forward (ADF) where relay only forwards the decoded data which causes resource wastage as the sources need to re-transmit the data which were not sent by the relay. This paper proposes a Hybrid-Combine-and-Forward (HCF) relaying scheme for a multi-user scenario to improve the Quality-of-Support (QoS) in a cost effective manner. With the HCF scheme, the relay dynamically performs AF on some of the received signals while DF on the rest, and stores them within a communication cycle. This decision is taken by the relay based on the Instantaneous Signal-to-Noise Ratio (SNR i ) of …
