Abstract
An algorithm for blind Doppler frequency estimation from orthogonal frequency division multiplexing (OFDM) signals transmitted by low Earth orbit (LEO) satellites is developed. A method for resolving the ambiguity in the Doppler estimate is also discussed. Two sets of experimental results are presented. The first demonstrates blind Doppler estimation from terrestrial fifth-generation (5G) signals on a mobile ground vehicle, achieving 14.5 Hz Doppler root mean-squared error (RMSE). The second demonstrates an unmanned aerial vehicle navigating using the proposed approach with emulated 5G signals from two Orbcomm LEO satellites for a period of 2 minutes, achieving 15.16 m position RMSE.
