Forney-style factor graphs are used for modeling space-frequency-coded MIMO OFDM
systems over frequency-selective fading channels. We analyze the Gaussian message
passing mechanism for the Alamouti scheme and linear transformation of the factor graph. A
new decision rule is derived in terms of the mean vector and covariance matrix of
modulation symbols. We employ the K-best algorithm with reduced complexity to justify the
effectiveness of our receiver.
