Motivated by the recently developed hybridcodingscheme for joint source-channel coding, this paper proposes a new codingscheme for noisy relay networks. The proposed codingscheme operates in a similar manner to the noisy network codingscheme, except that each relay node uses the hybridcodinginterface to transmit a symbol-by-symbol function of the received sequence and its quantized version. This codingscheme unifies both amplify-forward and noisy network coding and can strictly outperform both. The potential of the hybridcodinginterface for relaying is demonstrated through the diamond relay network and two-way relay channel examples.
