Zusammenfassung: | A receiver for detecting channel occupancy of a radio channel is provided. The receiver includes an oscillation circuit configured to generate an oscillation signal. The oscillation circuit is configured to alternate a frequency of the oscillation signal between at least two different frequency values. Further, the receiver includes a down-conversion circuit configured to generate, based on a received radio frequency signal and the oscillation signal, one of an in-phase component and a quadrature component of a baseband signal. The receiver additionally includes a processing circuit configured to calculate, based on the in-phase component or the quadrature component, a signal power of the radio frequency signal. |
