A Doppler Compensation Applique for LTE-Based Aeronautical Mobile Telemetry
Abstract
We have identified and resolved major challenges in implementing Aeronautical Mobile Telemetry (AMT) in a wireless LTE network. The key challenge involves addressing the high Doppler shifts that are likely to be present in typical AMT scenarios. Our proposed LTE-based AMT system includes a commercial off the shelf (COTS) LTE mobile terminal combined with a Doppler estimator/compensator applique. The applique estimates the Doppler shift using signals transmitted by the terminal, and proactively compensates for it in the uplink signals transmitted over the air interface. This paper presents a description of the applique. A prototype of this applique has undergone extensive testing in the laboratory and in outdoor over-the-air live links to assess its performance in the field. The paper also provides a representative sample of the test results.
