What is the sound of a car engine? Well, actually, that depends very much on where you are! If you sit inside the car, and have time to listen to the engine, you’ll hear a constant humming of the machine. Quite a muffled sound, actually, because nowadays car manufacturers try to make sure that you hear as little of the engine sound as possible.

Doppler Shift Mitigation in Acoustic Positioning Based on Pedestrian Dead Reckoning for Smartphone
IEEE Transactions on Instrumentation and Measurement, 2021Acoustic localization is a viable solution for high-precision indoor positioning with current built-in smartphone sensors. However, the Doppler shift produces an additional error in the time difference of arrival (TDOA) estimation when the smartphone is ...

Analysis of the Underwater Multi-Path Reflections on Doppler Shift Estimation
IEEE Wireless Communications Letters, 2020For underwater target localization and tracking, accurate Doppler shift estimation is very important. In this letter, the analysis of the multi-path effect on Doppler shift estimation accuracy is conducted for the narrow-band acoustic underwater channels.

An Efficient Blind Doppler Shift Estimation and Compensation Method for LEO Satellite Communications
International Conference on Speech Technology and Human-Computer Dialogue, 2020Low earth orbit (LEO) satellite communication systems suffer a large and fast-varying Doppler shift which has to be estimated and compensated before any demodulation processing.
