    摘要: The goal of the invention is to keep the delay of a communication signal between a moving vehicle (mobile body) and a fixed base station constant. This is achieved by a Doppler compensation method for data to be transmitted within frames via radio transmission between a mobile body and some base station, both mobile body and base station comprise respectively a transceiver connected to an antenna for the radio transmission. The method comprises the step of determining the Doppler effect acting on the frames when transmitted as a signal through that radio transmission for a given speed and direction of motion of the mobile body with respect to the base station. It is then followed by the step to apply by the transceiver some sampling procedure comprising an allocation of different time delays to the signal, the different time delays being chosen following a law adapted to compensate the determined Doppler effect.
