Simulation and Evaluation of Car-to-Car Communication Channels in Urban Intersection Scenarios

This paper evaluates multiple antenna systems in realistic Car-to-Car (C2C) communication channels for urban intersection scenarios. With a three-dimensional ray-tracing simulation tool the channel characteristics are determined for various antenna positions and numbers of antennas. The results clearly show the advantage of multiple antenna systems. Suitable antenna positions are determinedthatallowtheoptimizationofthe channel capacity ( )However, in spite of the benefits of route specific infor- mation, the amount of data to be processed and transmitted presents a great challenge. Other road users as well as the surroundings influence the channel in a complex manner. It follows that a detailed knowledge about the inter-vehicle trans- mission channel is necessary for the design and optimization
