Abstract
Methods and systems for communication and sensing systems. The disclosed method includes, among other things, responsive to receiving a plurality of channel frequency response (CFR) measurements from an antenna operating at a low-bandwidth range, generating a channel state information (CSI) across a high-bandwidth range based on the plurality of CFR measurements and determining, based on the CSI, a Doppler shift across the high-bandwidth range.
Claims8
A device comprising:
- a transmitter coupled to at least one antenna;
- a receiver coupled to the at least one antenna;
- and
- a processing device coupled to the transmitter and the receiver, the processing device for performing operations comprising:
- responsive to receiving a plurality of channel frequency response (CFR) measurements from an antenna operating at a low-bandwidth range, generating, based on the plurality of CFR measurements, a channel state information (CSI) across a high-bandwidth range;
- and
- determining, based on the CSI, a Doppler shift across the high-bandwidth range.
