Abstract

The results of an evaluation of the impact of Doppler frequency shift on the capabilities of satellite communication links when using standard 5G smartphones as subscriber equipment in an NTN network based on low Earth orbit (LEO) satellites are presented. The assessment considered downlink (DL) and uplink (UL) communication paths of the NTN 5G network to determine the availability of such a communication channel with and without a Doppler shift compensator on the LEO satellite. A simulation study of the NTN satellite constellation operating in the S- and L-bands was conducted to compare the channel availability time with and without the Doppler frequency shift compensator. The obtained estimates made it possible to analyze the problems of using commercially available smartphones already operating in 5G networks for communication through such channels and the impact of Doppler frequency shift on them.
