RSRP-Based Doppler Shift Estimator Using Machine Learning in High-Speed Train Systems
IEEE Transactions on Vehicular Technology, 2021In the fifth-generation (5G) high-speed train (HST) system operating in the millimeter-wave (mmWave) band, a much higher Doppler shift occurs. Doppler shift severely degrades reception performance in orthogonal frequency division multiplexing (OFDM ...

Micromotion Detection of Moving and Spinning Object Based on Rotational Doppler Shift
IEEE Microwave and Wireless Components Letters, 2018The detection method of the moving and spinning object is proposed based on rotational Doppler shift in this letter. The wave carrying orbital angular momentum (OAM) is transmitted to illuminate a moving and spinning object, and the echo is modulated by ...

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.
