“Doppler Estimation for Aeronautical Satellite OFDM System”

Abstract: Air traffic and onboard data access services are expected to have tremendous growth. To meet the challenges, the Orthogonal Frequency Division Multiplexing (OFDM) can be deployed to enable the increased usage of broadband services onboard. The Doppler effect is one of the major issues in implementing OFDM modulation in the aeronautical satellite communication system since the received carrier frequency shifts and Doppler spread result in intercarrier interference (ICI). In this seminar, we will evaluate the Doppler frequency estimation using the parametric method, and Angle of Arrival technique (AoA) to reduce the impact of Doppler effect on system performance. The MUSIC, Eigenvector and Minimum Norm algorithms are used to estimate the subcarriers’ shift of received OFDM symbol. We can find that the both methods can be reducing the effect of ICI in aeronautical satellite environment.
