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.

The Doppler light (wavelength or frequency) shift depends on relative velocity alone. Demanding Lorentz invariance of the light wave phase, we show that the Doppler shift is reciprocal: any two observer-sources will find a reciprocal Doppler light shift which allows each of the two to identify the relative velocity vector. Time dilation, i.e.

Effect of Sensor Motion on Time Delay and Doppler Shift Localization: Analysis and Solution
IEEE Transactions on Signal Processing, 2019This paper investigates active localization of a stationary object using time delay alone or together with Doppler shift measurements observed by a number of dynamic monostatic sensors having collocated transmitters and receivers, where the sensor motion

Initial Satellite Access Authentication Based on Doppler Frequency Shift
IEEE Wireless Communications Letters, 2021The future mobile system shall be able to support satellite access to provide an ubiquitous wireless connection service. Satellite communication is vulnerable to spoofing attacks due to the open nature of wireless channels, especially for the downlink ...

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.

Direct Position Determination Sensitivity to NLOS Propagation Effects on Doppler-Shift
IEEE Transactions on Signal Processing, 2019In this paper, we consider the Direct Position Determination (DPD) algorithm for Doppler-shift based localization of radio-emitters. The DPD emitter location estimate is the location candidate that maximizes the largest eigenvalue of a location-dependent

Einstein Shift and Doppler Shift
Nature, 1925MAY I ask whether the Einstein shift of spectral lines is supposed to be due to some change of frequency associated with an atomic occurrence while generating waves, or to direct influence of the gravitational potential on ether vibrations after they are generated.

Predictive Communication and Its Application to Vehicular Environments: Doppler-Shift Compensation
IEEE Transactions on Vehicular Technology, 2018We introduce predictive communication algorithms for channel estimation and equalization in vehicular environments. The proposed concept makes use of vehicular sensors combined with unique properties of surrounding environment to predict future changes ...
