Abstract: A transmitter of a radar system repeatedly transmits a first OFDM symbol into a scene to be characterized during a first time interval, and repeatedly transmits, during a second time interval that occurs after the first time interval, a second OFDM symbol into the scene. A receiver of the radar system generates a first channel response estimate for a first section of the scene based on: received reflections of the first symbol, at least one of which was received during transmission of the second OFDM symbol in the second time interval, and a first channel response estimate for a second section of the scene based on the first channel response estimate for the first section of the scene, received reflections of the first symbol, and received reflections of the second symbol. The receiver detects objects present in the scene based on the first channel response estimate for the first section of the scene and the first channel response estimate for the second section of the scene.

Abstract: A multifunctional radar transmitter may comprise bus interface circuitry and beamforming circuitry. The beamforming circuitry, with use of a plurality of beamforming coefficients, is operable to process a plurality of baseband signals to generate a millimeter wave radar burst corresponding to a radiation pattern that comprises a first lobe and a second lobe, where the first lobe is at a first angle and the second lobe is at a second angle. The bus interface circuitry is operable to receive, from a first receiver, an indication of interference from the second lobe present at the first receiver. The beamforming circuitry is operable to adjust, based on the indication of interference, the beamforming coefficients such that the second lobe is redirected to a third angle.

Abstract: A system comprises a multifunction radar receiver that in turn comprises processing circuitry and front-end circuitry. The front-end circuitry is operable to receive a millimeter wave burst via a plurality of antennas to generate a plurality received signals. The processing circuitry is operable to receive a first scene representation that is an aggregate of scene representations generated by one or more other radar receivers. The processing circuitry is operable to process the received signals to generate a second scene representation. The processing circuitry is operable to compare the first scene representation and the second scene representation and generate a difference scene based on the comparison. The processing circuitry is operable to generate a control signal based on the difference scene.

Abstract: A first microwave backhaul transceiver may comprise a plurality of antenna elements. The transceiver may determine atmospheric conditions between it and one or more potential link partners, and adjust a radiation pattern of the plurality of antenna elements based on the determined atmospheric conditions. A first radiation pattern of the plurality of antenna elements may correspond to a first microwave backhaul link between the first microwave transceiver and a second microwave backhaul transceiver. A second radiation pattern of the plurality of antenna elements may correspond to a second microwave backhaul link between the first microwave transceiver and a third microwave backhaul transceiver. The transceiver may adjust the radiation pattern based on characteristics of data to be transmitted, and based on a routing table it maintains.

Abstract: Methods and systems are provided for aligning devices separated by physical barriers. A first electronic device may be paired with a second electronic device, with the first electronic device and the second electronic device being on opposite sides of a physical barrier. Wireless communication of signals between the first electronic device and the second electronic device may then be configured to nullify or reduce signals in areas other than a region within the barrier between a signal transmission component of the first electronic device and a signal reception component of the second electronic device. Feedback for enabling aligning the first electronic device with the second electronic device may be provided, such as to user of one or both of the first electronic device and the second electronic device. Providing the feedback may include generating visual and/or audio cues to enable the aligning.

Abstract: A system comprises a plurality of antenna elements, a transmitter circuit, and first and second receiver circuits. The transmitter is operable to: transmit, via a first antenna element, a series of signals having a calibration component and each of the signals being generated with a different configuration of the transmitter circuit; and select a configuration for a future transmission based on a signal metric. The first receiver circuit is operable to: receive the signal via a second antenna element; and detect the calibration component in the signal to generate a first calibration signal. The second receiver circuit is operable to: receive the signal via a third antenna element; detect the calibration component in the signal to generate a second calibration signal; combine the first and second calibration signals to generate a combined calibration signal; and generate the signal metric based on the combined calibration signal.

Abstract: A radar system comprises a transmitter and a receiver. The radar system is operable to define a near range and a far range. The radar system is operable to, during each one of a plurality of time intervals, repeatedly transmit, via the transmitter, a plurality of OFDM symbols. The transmitter is operable to select a transmit power for the transmission during the one of the time intervals based on from which of the near range and the far range reflections of the OFDM symbols are to be received during the one of the time intervals. The receiver is operable to receive reflections of the OFDM symbols, and process, in the receiver, the reflections of the OFDM symbols to detect objects within the near range and the far range.

Abstract: A first mobile consumer electronic device comprises a broadband near-field communications (BNC) transceiver and is configured to operate as a main processing unit for a second mobile consumer electronic device that is configured as a thin-client. The first mobile consumer electronic device may capture, via the BNC transceiver, a signal over a range of frequencies that spans multiple frequency bands which are licensed by a regulatory authority. The first mobile consumer electronic device may process the captured signal to determine which of the multiple frequency bands are not currently in use by other devices. The first mobile consumer electronic device may select a plurality of the frequency bands. The first mobile consumer electronic device may transmit, via the BNC transceiver, a signal over the selected plurality of frequency bands at a determined strength, where the signal carries video data destined for the second mobile consumer electronic device.

Abstract: Aspects of a method and system for high-speed, low-power optical communications are provided. In one embodiment, a system for optical communications comprises a digital-to-analog converter (DAC), a driver, and a transmit optical subsystem. The DAC is operable to receive a digital code of a plurality of digital codes and output an analog current signal having an analog current level of a plurality of analog current levels. The driver is operable to condition the analog current signal output from the digital-to-analog converter. The transmit optical subsystem is operable to generate an optical power signal from the conditioned analog current signal. A mapping between the plurality of digital codes and the plurality of analog current levels is dynamically controlled according to one or more characteristics of the optical power signal. The one or more characteristics comprise or a symbol amplitude sensitivity and/or a nonlinearity that may be temperature dependent.
