摘要

Orthogonal frequency division multiplexing (OFDM) will be widely used in aviation mobile communications for its own advantages, but the complex channel environment and the inter-carriers interference (ICI) caused by Doppler frequency offset will do harm to its performance. Based on the general channel model of aviation mobile communications, the ICI mechanism is analyzed, and the lowpass filtering in frequency domain is adopted to restrain the influence from ICI and channel noise to affect the least square (LS) channel estimation based on comb-type pilot tone. Through simulation, the improved LS meets the demand of aviation mobile communications with mobile speed up to 1500 km/h because of its high estimation precision, strong resistance to ICI and easy realization.
