In this work, two peak-to-average power ratio (PAPR) reduction techniques are proposed for cooperative ortho- gonal frequency division multiplexing (OFDM) communication systems using relay selection with the amplify-and-forward (AF) protocol. The proposed techniques are based on a classical relay selection method that uses the channel capacity as the selection criterion. In order to select the best relay, the new methods consider not only the channel capacity used by the classical relay selection technique, but also the PAPR. Simulations results are provided to illustrate the behavior of the proposed techniques.
