In this paper, we investigate the energy efficiency maximization problem of analog network coding (ANC) based two-way relay (TWR) assisted cellular network under quality of service (QoS) constraints through transmit power optimization. Circuit power cannot be ignored since it influences energy efficiency greatly. However, the difficulty is that maximizing energy efficiency is shown to be non-convex in TWR-assisted network, and cannot be equivalent to the convex minimizing transmit power because… CONTINUE READING
