In this paper, the authors show the performance improvement in a Co-Operative Orthogonal Frequency Division Multiplexing (CO-OFDM) network employing amplify-and-forward & decode-and-forward relaying strategies under the influence of both Carrier Frequency Offset (CFO) and Timing Offsets (TO). Multiple distributed nodes in cooperative networks are generally subject to carrier frequency offset and timing offsets. Cooperative transmission, in which a source and relay cooperate to send a message to a destination, can provide diversity against fading in wireless networks.
