In this paper, the performance of Alamouti coded orthogonal frequency division multiplexing (OFDM) systems over car-to-car (C2C) fading channels correlated in time and space is analyzed. Taking different geometrical scattering models into account, a generalized expression of the time-variant transfer function (TVTF) is derived for wideband multiple-input multiple-output (MIMO) C2C channels. We present a generalized expression for the bit error probability (BEP), which will be used to describe the performance of Alamouti coded OFDM systems over different types of C2C channel models, such as the rectangle model, the tunnel model, the street model, and the curve model. The effect of the maximum Doppler frequency and the antenna element spacing on the system performance is discussed. Furthermore, the proposed generalized model allows us to study the impact of the parameters of the geometrical model on the BEP. The proposed procedure enables us to investigate the system performance using different kinds of C2C fading channel models in a straightforward and time-efficient manner.
