Abstract
On the basis of the characteristics of the LEO channel,a pilots-aided frequency offset estimation algorithm for OFDM systems is proposed.The simulation results are presented in error probability for integer frequency offset estimation and in mean square error(MSE)for fructional frequency offset estimation.They show that the proposed algorithms are available for frequency offset correction of OFDM systems on LEO satellite channel.
