Abstract: Techniques provided herein are directed toward enabling short-range proximity detection using radar sensors by reducing or eliminating OTA leakage. Embodiments generally include performing spatial cancellation by using a plurality of transmit/receive pairs of antenna elements to implement analog and/or digital leakage cancellation on the transmit and/or receive side. According to some embodiments null space projection cancellation, OTA leakage tracking, or adaptive minimum variance distortionless response (MVDR) beamforming may be performed to help preserve of the OTA leakage cancellation efficacy over time.

Abstract: Techniques for performing gesture recognition with an electronic device are disclosed where the electronic device has a wireless communications capability using beamforming techniques and includes a plurality of millimeter wave antenna modules, each antenna module including at least one transmit antenna and at least one receive antenna, the antennas being operable in one or more frequency ranges greater than 20 GHz. Performing gesture recognition includes: simultaneous operation of the at least one transmit antenna and the at least one receive antenna so as to provide a radar capability; and detecting a presence and motion of a reflective object by analyzing magnitude and phase of signals received by the at least one receive antenna and resulting from reflection of signals transmitted by the transmit antenna and reflected by the reflective object.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may receive an indication of a selected digital pre-distortion (DPD) kernel from multiple DPD kernels. The apparatus may store multiple envelope values associated of with samples of an in-phase/quadrature (I/Q) signal and select a subset of envelope values based at least in part on the selected DPD kernel. The apparatus may generate, using the subset of envelope values and a look-up-table (LUT) component, an envelope computation value. The apparatus may store multiple computational values associated with the samples and select, based at least in part on the selected DPD kernel, at least one subset of computational values. The apparatus may generate an output sample that includes DPD based at least in part on combining the envelope computation value with the at least one subset of computational values. Numerous other aspects are described.

Abstract: Methods, systems, computer-readable media, and apparatuses for radar processing based on a combination of analog beamforming, digital beamforming, and virtual arrays are described. In certain embodiments, a radar receiver receives signals simultaneously transmitted, i.e., concurrently, from a radar transmitter. Each transmitted signal corresponds to the same transmit signal, but with a respective phase being applied. The radar receiver generates, based on the received signals, a virtual array response corresponding to an array of virtual antennas. The virtual array response covers a subset of directions within a field of view to be scanned. In some embodiments, the transmissions from the radar transmitter are generated using analog beamforming, and the virtual array response generated using digital beamforming. In other embodiments, the transmissions from the radar transmitter are generated using digital beamforming, and the virtual array response generated using analog beamforming.

Abstract: A transceiver having a virtual array is disclosed that includes a transmit antenna array and a receive antenna array. The transmit antennas are spaced apart by a transmit array spacing. Similarly, the receive antennas are spaced apart by a receive array spacing. One of the receive and transmit arrays has more antenna elements than a ratio of either the transmit array spacing divided by the receive array spacing or of the receive array spacing divided by the transmit array spacing.

Abstract: Power saving techniques for radar-based proximity sensing can include conducting proximity scans with a radar system in an omnidirectional proximity sensing mode in which signals are transmitted without directionality. Once an object is detected within a threshold proximity, the radar system can then switch to a directional proximity sensing mode to provide accurate directional detection capabilities in a desired field of view (FOV).

Abstract: A two-stage technique for compressing radar data is disclosed in which, in the first stage, Constant False Alarm Rate (CFAR) compression is conducted using a median calculated from at least one dimension of radar data, which is then used to determine filtering threshold values for all dimensions of the radar data. The radar data is then compressed by filtering the radar data based on the filtering threshold values. In the second stage, peak detection is then performed on the compressed data to identify detected objects (targets). These and other embodiments are described herein.
