  • Electronic Devices with Leakage Cancellation for Range Detection
    Publication number: 20230296751
    Abstract: An electronic device may include wireless circuitry with a transmit antenna and a receive antenna. Signal bursts may be transmitted by the transmit antenna. A phase shifter may be toggled between a first state that applies a first phase shift and a second state that applies a second phase shift to the signal bursts. The second phase shift may be approximately 180 degrees out-of-phase with the first phase shift. A receive path may receive first reflected signals while the phase shifter is in the first state and second reflected signals while in the second state. The first and second reflected signals may be used to cancel the effects of on-chip leakage or DC offset to recover a signal-of-interest associated with reflection of the signal bursts off an external object. The signal-of-interest may be used to detect a range to the external object.

  • Real time analog front end response estimation for sensing applications
    Patent number: 11012262
    Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a wireless device to perform improved channel estimates for sensing applications such as ranging. The wireless device may determine noise characteristics, e.g., a spectrum of the variance of noise on a channel and may use the noise characteristics to estimate a response of an analog front end of the wireless device. The wireless device may correct a channel estimate based on the estimated response of the analog front end.
