Abstract: An apparatus is disclosed for radar interference mitigation using a pseudorandom offset. The apparatus includes an antenna array and a wireless transceiver. The wireless transceiver is coupled to the antenna array and is configured to transmit, via the antenna array, a radar transmit signal based on at least one pseudorandom offset. The wireless transceiver is also configured to receive, via the antenna array, at least a portion of another radar transmit signal from another apparatus. The wireless transceiver is additionally configured to receive, via the antenna array, a radar receive signal that includes a portion of the radar transmit signal that is reflected by an object. At a given time, a frequency of the radar receive signal is different than a frequency of the radar transmit signal based on the at least one pseudorandom offset.

Abstract: Apparatus and methods are disclosed for determining, on a small form factor 5G communication device, the range of a target object include receiving, at a receiving antenna of the small form factor communication device, a composite signal where the composite signal includes a target reflection signal and a mutual coupling (MC) leakage signal, generating a composite beat waveform by mixing the composite signal with an original signal, where the composite beat includes target beat and MC leakage beat waveform components, isolating the target beat waveform by subtracting from the composite beat waveform a weighted, k-delayed composite beat waveform, where for a configured k the target beat waveforms are uncorrelated and the MC leakage beat waveforms are correlated, and determining, using the target beat waveform, a range of the target object from the small form factor device.

Abstract: Some disclosed devices include a plurality of transmitter/receiver pairs configured for transmitting and receiving millimeter wave (mmWave) radar and a control system configured for obtaining, via a first transmitter/receiver pair, a first round-trip time for a first reflection from an object proximate the apparatus. The control system may be configured for obtaining, via a second transmitter/receiver pair, a second round-trip time for a second reflection from the object and for determining a position of the object based, at least in part, on the first round-trip time and the second round-trip time.

Abstract: Certain aspects of the present disclosure generally relate to a programmable multi-mode digital-to-analog converter (DAC) for generating a frequency-modulated signal. For example, certain aspects provide a circuit for sweeping a frequency of an output signal. The circuit generally includes a DAC having an input coupled to an input path of the circuit and an output coupled to an output path of the circuit, a first mixer selectively incorporated in the input path coupled to the input of the DAC, and a second mixer selectively incorporated in the output path coupled to the output of the DAC.

Abstract: An apparatus is disclosed for proximity detection using a hybrid-transceiver. In an example aspect, the apparatus includes a hybrid transceiver coupled to a first antenna and a second antenna. The hybrid transceiver is configured to generate, in a digital domain, a digital baseband radar signal. The hybrid transceiver is also configured to transmit, via the first antenna, a radio-frequency transmit signal that is derived from the digital baseband radar signal. Via the second antenna, the hybrid transceiver is configured to receive a radio-frequency receive signal, which includes a portion of the radio-frequency transmit signal that is reflected by an object. In an analog domain, the hybrid transceiver is configured to generate an analog receive signal that includes a beat frequency, which is indicative of a frequency offset between the radio-frequency transmit signal and the radio-frequency receive signal. The analog receive signal is derived from the radio-frequency receive signal.
