Vehicular networks are perturbed by a wide range of noise sources which cause poor signal detection that accounts for high BER. Multipath propagation and shadowing are noise sources that are mitigated by channel equalization algorithms. However, channel equalization fails to enhance BER performance in high vehicular mobility conditions because of the prevalent Doppler shift. In this paper, received power enhancement realized by MIMO techniques is deployed to improve detection in high vehicular mobility conditions. Simulation results show that 2×2 MIMO system delivers 12 dB better than the conventional system based on single antenna configuration.
