  • Patent number: 11346918
    Abstract: An interrogation device, for locating a wireless device, includes a receiver and digital processing circuitry. The receiver includes one or more receiver stages having adjustable gains, and is configured to receive from the wireless device a signal that carries a packet including a direction-finding field, wherein, during reception of the direction-finding field, multiple different temporal sections of the received signal traverse different wireless channels due to switching among different antennas in the interrogation device or in the wireless device and thus have multiple different received-signal levels. The digital processing circuitry is configured, based on the multiple received temporal sections of the signal during reception of the direction-finding field, to (i) adapt the adjustable gains of the receiver stages and (ii) estimate a position of the wireless device.

  • Patent number: 10574393
    Abstract: The present disclosure describes methods and apparatuses for phase-based cyclic redundancy check (CRC) verification for wireless communication. In some aspects, a soft phase value and a sliced phase value are received for a symbol of a data packet, the data packet received via a wireless interface. An error measurement is determined for the symbol based on the soft phase value and the sliced phase value. The error measurement for the symbol is then compared to an error measurement threshold for detecting symbol-level errors in the data packet. Based on the error measurement exceeding an error measurement threshold, a bit error can be detected in the data packet, which may have passed CRC. By detecting the bit error despite a CRC pass, the bit error can be indicated to higher-level entity of the wireless interface. This can be effective to prevent the bit error from impairing operation of the higher-level entity.
