We apply and extend the packet detection and frequency synchronization technique by Schmidl and Cox to a multi-antenna receiver for Wireless Access in Vehicular Environments (WAVE) according to IEEE 802.11 p. We investigate the resulting performance enhancements due to the use of multiple antennas from recently carried out real-world experiments in vehicular scenarios. The evaluation shows that the amount of detected frames can be increased by up to 27 %, if two receive antennas and an appropriate combining scheme, for the whole synchronization process, is used.
