  • Patent number: 11914049
    Abstract: A mobile device may be configured to improve measurement of carrier phase (CP) in received satellite signals for satellite positioning system (SPS) operations. For example, this may enable an SPS receiver to measure CP of at least a first positioning signal and a second positioning signal each received from the same satellite vehicle. A corrected CP of the first positioning signal may be estimated based on the measured CP of the first positioning signal and on the measured CP of the second positioning signal.

  • Patent number: 11906637
    Abstract: A device may use Precise Point Positioning (PPP) correction information to generate Real Time Kinematic (RTK) correction information that can be sent to other devices for RTK-based positioning. In particular, according to some embodiments, the first device having access to PPP correction information may obtain the PPP correction information and generate RTK correction information by determining a virtual RTK base station location and generating, based on the PPP correction information, a virtual Multi-Constellation Multi-Frequency (MCMF) measurement corresponding to the determined virtual RTK base station location. This virtual MCMF measurement (and/or data derived therefrom) can then be sent to other devices as RTK correction information.

  • Patent number: 11906614
    Abstract: This document describes techniques and systems directed at slow-time modulation for multiple radar channels. A set of transmit channels are modulated using code sequences to phase-modulate transmission signals. A second set of transmit channels are modulated using the same codes for phase modulation as well as using a frequency phase shift. Demodulation is achieved by multiplying received signals by the code sequences. Fast Fourier transforms (FFT) are applied to the received signals to generate a range-Doppler map for each receive channel. A non-coherent integration is performed on the range-Doppler maps to form a range-Doppler average map. The range-Doppler average map is shifted by the frequency phase shift, and the minimal of the range-Doppler average map and the shifted range-Doppler average map is retained. These techniques may reduce the impact of signal residue and increase angular resolution by enabling multiple transmit channels to be utilized.

  • Patent number: 11906619
    Abstract: Techniques and apparatuses are described that implement a smart-device-based radar system capable of detecting user gestures in the presence of saturation. In particular, a radar system employs machine learning to compensate for distortions resulting from saturation. This enables gesture recognition to be performed while the radar system's receiver is saturated. As such, the radar system can forgo integrating an automatic gain control circuit to prevent the receiver from becoming saturated. Furthermore, the radar system can operate with higher gains to increasing sensitivity without adding additional antennas. By using machine learning, the radar system's dynamic range increases, which enables the radar system to detect a variety of different types of gestures having small or large radar cross sections, and performed at various distances from the radar system.

  • Patent number: 11892562
    Abstract: A performing device of an impulse-like gesture recognition system executes an impulse-like gesture recognition method. A performing procedure of the impulse-like gesture recognition method includes steps of: receiving a sensing signal from a sensing unit; determining a prediction with at least one impulse-like label according to the sensing frames by a deep learning-based model; and classifying at least one gesture event according to the prediction. The gesture event is classified to determine the motion of the user. Since the at least one impulse-like label is used to label at least one detection score of the deep learning-based model, the detection score is non-decreasing, reaction time of the at least one gesture event for an incoming gesture is fast, rapid consecutive gestures are easily decomposed, and an expensive post-processing is not needed.
