With around two billion children waiting for presents tonight, scientists say Santa would need to make a journey equivalent ...

At present, The spoof interference detection algorithms commonly utilize temporal consistency and other time-frequency information ... involving relative Direction of Arrival (DoA) and Doppler shift ...

Depending on the initial ML frequencies, it can induce either a 279.73-GHz or a 13-octave-span larger (3.63-THz) frequency shift while maintaining ML, far beyond the cavity’s intrinsic continuously ...

Because noncoherent orthogonal frequency division multiplexing with M-ary frequency shift keying (OFDM-MFSK ... including low signal-to-noise ratio (SNR), large Doppler effect, and time-varying ...

To further our knowledge of very-low-frequency signals received via the ... but the equipment used did not allow the variations of doppler shift with time to be resolved to better than 30 min.

[Kristina] hopes to take all of the data gathered during the event to observe the doppler effect that is expected to occur. The project requires a large amount of volunteers to listen in to the ...

The goal was to decode the frequency-shift-keyed (FSK) signal into an 8-bit parallel output, and maybe drive a seven-segment display as the characters came off the tape at a screaming 300 baud.
