  • Patent number: 10330771
    Abstract: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.

  • Patent number: 10330778
    Abstract: We disclose a lidar system that includes a modulator-based probe-light generator and a coherent optical receiver. The probe-light generator uses tunable carrier-suppressed single-sideband modulation to generate frequency-chirped optical pulses for the optical-probe beam directed at the target. The coherent optical receiver uses a homodyne detection scheme in which a split portion of the optical-probe beam is used as an optical local oscillator signal for detecting a corresponding optical beam reflected by the target. The resulting electrical RF signals generated by the receiver can be processed, e.g., using a disclosed signal-processing method, to determine one or both of the distance to the target and the velocity of the target.

  • Patent number: 10330782
    Abstract: A method for ultrasonic imaging a volume behind a barrier includes placing an array of elements of a probe adjacent the barrier. The local thickness and the sound speed in the barrier are estimated. A plurality of sub-apertures are defined in the array of elements, each sub-aperture defined by a different sub-set of adjacent ones of the array of elements. Ultrasonic waveforms are collected from each of the sub-apertures by focusing each sub-aperture approximately at the inner surface of the barrier. The ultrasonic waveforms through each of the sub-aperture elements are combined to generate a combined A-mode waveform. A profile of an inner surface of the barrier adjacent the probe is extracted based upon the combined A-mode waveforms. A correction is calculated based upon the profile of the inner surface. The volume behind the barrier is scanned using beamforming based upon the correction to generate an image of the volume.

  • Patent number: 10330783
    Abstract: The present disclosure describes methods and apparatuses for location service offload for Bluetooth positioning. In some aspects a Bluetooth radio frequency (RF) signal is sampled by a Bluetooth transceiver to produce a set of samples corresponding to an advertisement packet and the set of samples are stored in a shared memory. Another transceiver is signaled that the set of samples are stored in the shared memory, causing the other transceiver to generate the Angle of Arrival (AoA) of the Bluetooth RF signal. A signal is received from the other transceiver indicating that the generated AoA is available in the shared memory. The generated AoA is read from the shared memory by the Bluetooth transceiver and sent to a host processor. By so doing, data transfer between the Bluetooth transceiver and the host processor is reduced, as well as, reducing the computational load on the host processor.

  • Patent number: 10330786
    Abstract: Various technologies for mitigating interference in stretch-processed SAR imagery are described herein. Stretch-processed SAR data is received at a computing device. The stretch-processed (or deramped) SAR data is then reramped, thereby removing frequency-variant components of narrowband interference signals in the deramped data. A frequency-domain transform is executed over the reramped data to generate a spectral characteristic of the reramped data. A spectral notch filter is applied to frequency bands corresponding to the peaks of the spectral characteristic in order to filter out the narrowband interference signals. An inverse frequency-domain transform can then be executed over the filtered spectral characteristic to return to a phase-history representation of the SAR data. The phase history resulting from the inverse frequency-domain transform is a ramped phase history, which can then be deramped prior to use in connection with generating images of the scanned scene.
