Method for Doppler frequency offset correction in a cellular radio communication system with a base station and a mobile unit on board of a vehicle moving with high velocity, in particular an aircraft.

摘要

The method involves determining (2) signal transit time between a base station and a mobile unit at defined points in time and transmitted to the mobile unit. The distance to the base station is derived (3) by the mobile unit from the respective signal transit time for a point in time. The change of the distance to the base station is determined (4) for successive points in time. A correction value for the natural frequency of the mobile unit is determined (5) based on time difference between the successive points in time and a speed of the aircraft.
