Abstract :
Analog network coding is considered in relay network to avoid the spectrum loss introduced by half-duplex property of the relay mode. Transmission rate is mainly concerned point by the previous researches. However, as the desire of green radio communication, energy-efficiency is more and more considered in the system design recently. In this paper, several high energy-efficiency schemes are proposed in multiple relays cooperative networks with analog network coding. The high energy-efficiency schemes are designed to minimize the overall energy consumption when the certain transmission rate is achieved. The numerical simulations show that the proposed schemes are very close to the lower bound of energy consumption.
