Novel frequency offset estimation for IEEE 802.11p standard in V2V channels

Wen-Jeng Lin, / I-Cheng Liu, / Jung-Shan Lin,

For inter-vehicle communications, the IEEE 802.11p standard has been employed in the U.S. and Europe. This configuration is an OFDM-based system, so it still has to cope with the issue of frequency synchronization. In this paper, a pilotaided estimation technique is developed for the compensation of frequency offset in vehicle-to-vehicle (V2V) channel environments. The proposed synchronization algorithm utilizes the correlation between two identical halves of a training sequence after the appropriate choice of coarse compensation. As a result, the estimation method indeed has the potentials to further enhance the mean square error (MSE) performance compared with the other conventional schemes. Some simulation results are given to illustrate the advantages of the proposed frequency offset estimation scheme for vehicular communications.
