Abstract
A receiver includes an ultra-wideband, UWB, communication unit configured to operate in a radar mode and to receive a synchronization signal transmitted by a transmitter, and a synchronization unit operatively coupled to the UWB communication unit. The synchronization unit is configured to estimate a carrier frequency offset from the synchronization signal, derive a reference time from the synchronization signal, and derive a time window for the reception of a radar packet by the UWB communication unit. The time window is derived from the estimated carrier frequency offset and the reference time. A corresponding method of operating a receiver also is disclosed.
Claims20
A receiver, comprising:
- an ultra-wideband, UWB, communication unit configured to operate in a radar mode and to receive a synchronization signal transmitted by a transmitter;
- a synchronization unit operatively coupled to the UWB communication unit, wherein the synchronization unit is configured to:
- estimate a carrier frequency offset from the synchronization signal;
- derive a reference time from the synchronization signal;
- derive a time window for the reception of a radar packet by the UWB communication unit, wherein the time window is derived from the estimated carrier frequency offset and the reference time.
A radar system comprising:
- a transmitter that includes a first ultra-wideband, UWB, communication unit configured to operate in a radar mode and to transmit a synchronization signal;
- and
- a receiver that includes
- a second UWB communication unit configured to operate in the radar mode and to receive the synchronization signal transmitted by the transmitter, and
- a synchronization unit operatively coupled to the second UWB communication unit, wherein the synchronization unit is configured to
- estimate a carrier frequency offset from the synchronization signal,
- derive a reference time from the synchronization signal, and
- derive a time window for the reception of a radar packet by the second UWB communication unit, wherein the time window is derived from the estimated carrier frequency offset and the reference time.
A method of operating a receiver, comprising:
- receiving, by an ultra-wideband, UWB, communication unit included in a receiver, a synchronization signal transmitted by a transmitter;
- estimating, by a synchronization unit included in the receiver, a carrier frequency offset from the synchronization signal;
- deriving, by the synchronization unit, a reference time from the synchronization signal;
- deriving, by the synchronization unit, a time window for the reception of a radar packet by the UWB communication unit, wherein the time window is derived from the estimated carrier frequency offset and the reference time.
