A transceiver may include a transmit path and a receive path that are each coupled to a radio frequency (RF) interface, and a self-interference canceller (SIC). The SIC is coupled between the transmit and the receive paths. The SIC is configured to cancel a self-interference signal from a received signal on the receive path based on a transmit signal on the transmit path.

Self-interference canceller

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.

Receiver and a method for detecting channel occupancy of a radio channel

Methods and systems for calibrating a receiver utilizing a noise signal generated by a power amplifier associated with a transmitter are provided. A calibration method or mode includes generating a noise signal with a power amplifier associated with a transmitter of the transceiver; processing the noise signal with the receiver to generate a received signal; and calibrating the receiver based at least on the received signal.

Receiver calibration using power amplifier noise

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.

Unique frequency plan and baseband design for low power radar detection module

Some demonstrative embodiments include apparatuses, devices, systems and methods of radar detection. For example, an apparatus may include a first detector component to detect energy over a wireless communication channel; a second detector component to detect a signal over the wireless communication channel, and to determine at least a classification of the signal as a radar-type or a non-radar type; a storage component to store radar detection information corresponding to signals detected by the second detector component, the radar detection information including at least the classification of the signal and one or more characteristics of the signal; and a controller to activate the second detector component upon detection of the energy by the first detector component, the controller configured to cause a radar-detection analysis of the radar detection information corresponding to a predefined time period.

Apparatus, system and method of radar detection

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.
