This paper proposes two new techniques of PAPR reduction for cooperative OFDM communication systems using the fixed AF transmission protocol, the proposed techniques being based on subcarrier pairing methods. The performance of the proposed techniques is evaluated by means of computational simulations, showing the efficiency of the methods in reducing the PAPR at the relay, as well as in providing good SER and capacity.
