Energy-Efficient Power Allocation for Decode-and-Forward OFDM Relay Links

This paper investigates the power allocation aiming to optimize the energy efficiency for an OFDM two-hop relay link based on DF protocol. First, an equivalent single-hop link is used to replace the two-hop link, and the model of the energy efficiency is established. When modeling the energy efficiency of the link, the circuit power consumption is not only… CONTINUE READING
