In this contribution, we present performance evaluation
results for a multi-antenna receiver for Wireless Access in
Vehicular Environments (WAVE) according to IEEE 802.11p. The
analysis was performed by employing the Selection Combining
(SC), the Equal Gain Combining (EGC) and the Maximum
Ratio Combining (MRC) algorithms on recently carried out
real-world measurement data. We show that a well-engineered
diversity combining algorithm, applied to multi-antenna systems,
significantly improves the reliability and robustness, even under
poor receive conditions. The resulting performance enhancement
compared to the single antenna regime in case of the frame
success ratio (FSR) is increased up to 25 %. This is due to the
fact that all available information from both antenna branches
is utilized. Furthermore, we investigate the influence of different
driving directions on the system performance.
