Abstract: In high-speed train (HST) mobile communication systems, high-speed movement of trains causes significant dynamic variations in the Doppler shift, which pose major challenges to communication ...

Abstract: We propose a technique for extracting the Doppler shift and its rate from OneWeb’s Ku-band user downlink signals and demonstrate its suitability for opportunistic positioning. Since the ...

The discovery of the rotational Doppler effect (RDE) has opened new opportunities for detecting parameters of rotating targets. In recent years, the physical mechanisms underlying this effect have ...

In May 2024, Disney CEO Bob Iger announced Marvel would be shifting its focus to quality over quantity. Instead of four movies and TV shows per year, Marvel would scale back and only release two to ...

There was experiments to test the performance of the different positioning frameworks with Starlink satellites before year 2024. The results showed meter level ...
