Distributed Decode-Forward for Relay Networks
IEEE Transactions on Information Theory, 2017 A new coding scheme for general N-node relay networks is presented for unicast, multicast, and broadcast. The proposed distributed decode-forward scheme combines and generalizes Marton coding for single-hop broadcast channels and the Cover-El Gamal ...

Comparison of managed decode-and-forward scheme and common decode-and-forward scheme in cooperative communication systems [PDF]
Journal of Intelligent Procedures in Electrical Technology, 2015 In this paper, the symbol error rate of M-PSK modulation in managed relay scheme is computed. In the conventional technique, the relay always decodes the received signal and re-sends it to the destination. In the destination, the two copies of the signal
