Abstract :
In this paper the coefficient tracking synchronization algorithm is proposed for the compensation and the suitability of the fast channel fluctuation OFDM in the WAVE (wireless access in vehicular environments) system. The progress of standardization WAVE process, IEEE802.11p´s physical layer is considered on the coexistence of fading and frequency offset of OFDM channel to find the system performance ability and the comparing examination which is taken on the proposed method of coefficient tracking synchronization algorithm and the performance efficiency. Through the simulation result we also can see that the proposed system improves the channel estimation ability and offers an extra efficiency if compared to the existing method.
