N2 - Because the high DFO (Doppler Frequency Offset) of aviation channel caueses much ICI (Inter-Channel Interference) among subcarriers of AMBC (Aviation Mobile Broadband Communicaiotn) based on OFDM technology, which degrades the performace badly, a new method, ANTI-D (ANTI-Doppler by information aid), aiming at eliminating ICI and improving the performance, is presented with a view to the characteristics of the aircraft as a platform of AMBC. For there are many kinds of equipments, such as navigatioin equipments and surveillance equipments on an aircraft, the information of position and the vector of velocity of the aircrafts or ground stations around, called aid information, can be get in real time or near real time, to compute the DFO, according to which the compensation can be done. The simulation results show that ANTI-D based on aid information, resolves the ICI caused by DFO effectively, and makes AMBC get better performance in En-route phase as well as in Arrival phase.
