Analysis of a General Mixed Strategy for Gaussian Multiple Relay Channels
— In their landmark paper Cover and El Gamal proposed different coding strategies for the relay channel with a single relay supporting a communication pair. These strategies are the decode-and-forward and compress-and-forward approach. They also derived a general lower bound on the capacity of a relay network which relies on the mixed application of both strategies. So far, only parts of their work - the decode-and-forward and the compress-and-forward strategy - have been applied to networks with multiple relays This paper formulates a mixed strategy for Gaussian multiple relay networks using a combined approach of partial decode-andforward with N + 1 levels and the ideas of successive refinement with different side information at the receivers. After describing the protocol structure and presenting the achievable rates, we compare it with some special cases, e. g., multilevel decodeand-forward, distributed compress-and-forward and a mixed approach where one relay node operates in d...
