This paper introduces a novel multiple-input multiple-output (MIMO) car-to-car (C2C) channel model, which is based on a geometrical curved street scattering model. Starting from the geometrical model, a MIMO reference channel model is derived under the assumption of a combination of single- and double-bounce scattering in line-of-sight (LOS) and non-LOS (NLOS) propagation environments. The proposed channel model assumes an infinite number of scatterers, which are uniformly distributed on the outer and inner curves of the street. Expressions are presented for the three-dimensional (3D) space-time crosscorrelation function (CCF), the temporal autocorrelation function (ACF), and the two-dimensional (2D) space CCF. An efficient sum-of-cisoids (SOC) channel simulator is derived from the reference model. It is shown that the temporal ACF of the SOC channel simulator fits very well to that of the reference model. The validity of the derived reference model has been verified by demonstrating an excellent match between the temporal ACF of the reference model with that of the one-ring model.
