N2 - In this paper, we consider multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) amplify-and-forward relay channels. We analyze the maximum achievable diversity of the coded beamforming scheme in MIMO-OFDM relaying systems, and provide proper code designs and the subcarrier pairing criteria that yield the maximum diversity. The pairwise error probability is analyzed based on the assumption of correlated fadings among subcarriers. For systems with Nt source, Nr relay and Nd destination antennas with proper code design, we show that the maximum achievable diversity order is obtained as min(LhN tNr, LgNrNd), where Lh and Lg denote the number of channel taps of the first hop and the second hop channel, respectively.
