RSRP-Based Doppler Shift Estimator Using Machine Learning in High-Speed Train Systems

IEEE Transactions on Vehicular Technology, 2021
In 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, 2018
The 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 ...
