Abstract: An apparatus for a low-power radar detection (LPRD) receiver is proposed in this disclosure. The LPRD receiver comprises an analog-to-digital converter (ADC) circuit configured to receive an analog dynamic frequency selection (DFS) signal associated with a DFS channel in a DFS frequency band to generate a digital DFS signal. The ADC circuit comprises a finite impulse response (FIR) filter circuit configured to sample the analog DFS signal at an FIR sampling rate determined based on a predetermined frequency plan associated with the DFS frequency band to generate a sampled DFS signal; and an ADC conversion circuit configured to convert the sampled DFS signal to the digital DFS signal at an ADC conversion rate that is lower than the FIR sampling rate.

Abstract: The present disclosure relates to a transmitter for transmitting a transmit signal comprising a first signal portion and a second signal portion. The transmitter comprises a power amplifier configured to amplify the transmit signal. The power amplifier is prone to undesired gain variations during the first and the second signal portion. The transmitter further comprises a transmit feedback receiver coupled to an output of the power amplifier and configured to feed back the transmit signal to generate a fed back first signal portion and a fed back second signal portion. Processing circuitry is configured to determine a first gain relation between the fed back first signal portion and the first signal portion and to determine at least one second gain relation between the fed back second signal portion and the second signal portion. Power adjustment circuitry is configured to adjust a transmit power of the transmit signal according to a variation between the first gain relation and the second gain relation.

Abstract: 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.
