  • Publication number: 20210165083
    Abstract: Optical sensing apparatus includes at least one semiconductor substrate and a first array of single-photon detectors, which are disposed on the at least one semiconductor substrate, and second array of counters, which are disposed on the at least one semiconductor substrate and are configured to count electrical pulses output by the single-photon detectors. Routing and aggregation logic is configured, in response to a control signal, to connect the single-photon detectors to the counters in a first mode in which each of at least some of the counters aggregates and counts the electrical pulses output by a respective first group of one or more of the single-photon detectors, and in a second mode in which each of the at least some of the counters aggregates and counts the electrical pulses output by a respective second group of two or more of the single-photon detectors.

  • Patent number: 10955552
    Abstract: Depth-sensing apparatus includes a laser, which is configured to emit pulses of optical radiation toward a scene. One or more detectors are configured to receive the optical radiation that is reflected from points in the scene and to output signals indicative of respective times of arrival of the received radiation. Control and processing circuitry is coupled to drive the laser to emit a succession of output sequences of the pulses with different, respective temporal spacings between the pulses within the output sequences in the succession, and to match the times of arrival of input sequences of the signals to the temporal spacings of the output sequences in order to find respective times of flight for the points in the scene.

  • Patent number: 10491431
    Abstract: In the subject system, a receiver includes a feed forward circuit, a phase recovery circuit, and a feedback circuit. The feed forward circuit compensates for near reflections and provides an input to the phase recovery circuit and the feedback circuit. The phase recovery circuit performs phase recovery and provides phase recovery information to the feedback circuit. The feedback circuit adjusts and/or corrects a received symbol based at least in part on the received phase recovery information.

  • Patent number: 10419132
    Abstract: The continuous demand for capacity and the limited available spectrum in wireless and wired communication has led to reliance on advanced modulation techniques to dramatically increase the number of bits per hertz per second. This demand in capacity and using the higher order constellations shorten the link range, and as a result, system gain becomes an important characteristic. The modulation techniques described here improve the system gain by, e.g., as much as 2.5 dB in high order modulations such as 4096-QAM. The modulation techniques include reducing the peak to average ratio and adding shaping gain. These techniques dramatically improve the system capacity, system gain, power consumption and system cost.

  • Patent number: 8599828
    Abstract: A method and apparatus are provided for identifying a cell and a sub-frame by detecting a part of a secondary synchronization signal including a sequence of N OFDM symbols. For each OFDM symbol, the method obtains a set of metrics, each metric being associated with a predetermined combination of a cell identifier and a sub-frame alignment (CID/SF). For each metric, the method counts the number of times a metric exceeds a first predetermined threshold, delivering a summed value, and applies an M of N criterion to the summed value, delivering a ratio value. The ratios values are analyzed in order to identify the cell and the sub-frame, corresponding to a cell identifier and a sub-frame alignment, associated to a particular ratio value among the ratios values, which exceeds a second predetermined threshold.
