A street reference model of MIMO vehicle-to-vehicle fading channel

In future, cars will form a network with other cars and roadside data systems to exchange information that alerts the driver on traffic congestion, road conditions, and accidents. It is expected that vehicle-to-vehicle communication systems will play an important role in intelligent transportation systems. MIMO systems employ multiple transmit and multiple receive antennas, combined with the opportunities opened by large vehicle surfaces on which multielement antennas can be placed, makes MIMO techniques very attractive for vehicle-to-vehicle communications. In this paper, we propose an original street model for MIMO vehicle-to-vehicle fading channels, derived from this model, the analysis of statistical properties of transmit and the receive correlation functions is given, and some numerical results for the special case of isotropic scattering are presented. Our procedure provides also an important framework for studying the channel capacity of MIMO vehicle-to-vehicle channels, channel coding and wireless intelligent transportation systems planning.
