The MB-OFDM has been proposed as a good candidate to ensure Vehicle to Infrastructure communication (V&I). Fast moving vehicles present challenges for the proposed system especially for high mobility (250 km h1). The main objective in this study is to study and investigate the impact of Doppler shift on the quality of transmitted/received signal in terms of Bit Error Rate (BER) and the transmission range. A new solution based on the association of Maximum Likelihood (ML) and Extended Kalman Filter (EKF) algorithmis proposed and computer simulations are performed to confirm the reduction of Doppler impact on the signal quality. Also it is shown that for high value of speed, the new solution can effectively improve the transmission range of the MB-OFDM system
