  • Patent number: 10284985
    Abstract: Latency on different devices (e.g., devices of differing brand, model, vintage, etc.) can vary significantly and tens of milliseconds can affect human perception of lagging and leading components of a performance. As a result, use of a uniform latency estimate across a wide variety of devices is unlikely to provide good results, and hand-estimating round-trip latency across a wide variety of devices is costly and would constantly need to be updated for new devices. Instead, a system has been developed for crowdsourcing latency estimates.

    Abstract: Embodiments herein describe a network device (e.g., an access point) that dynamically arranges multi-user (MU) multiple input multiple output (MIMO) compatible client devices into MU-MIMO groups. That is, the network device uses network metrics and historical data to change the assignment of client devices in the MU-MIMO groups which may improve MU-MIMO efficiency by reducing the amount of power that leaks between the clients devices in the group. In one embodiment, the AP identifies a MU-MIMO group based on a performance evaluation such as evaluating network metric or determining if the group is underutilized. The AP can replace the identified MU-MIMO group with a substitute MU-MIMO group where the substitute MU-MIMO group is selected based on historical data corresponding to the client devices assigned to the substitute MU-MIMO group.

However, if the duration of the sampling period exceeds the time threshold for the sampling period, the method includes dividing the sampling period into a finite number of sub-intervals and processing the data samples in each sub-interval so as to produce a respective intermediate result for each sub-interval. Each of these intermediate results is stored directly after it is produced, and these stored intermediate results are processed so as to estimate the maximum time interval error.

  • Patent number: 9989590
    Abstract: A self-test circuit is driven by a multiphase clock signal which includes N number of clock signals in same cycle having phases from first to N-th phases each phase-shifted by 1/N of the cycle. The self-test circuit includes a data selecting circuit, a serialization circuit, and a logical test circuit. The data selecting circuit switches input data that are input as M-bit wide parallel data to the self-test circuit, between normal data and test data for logical test. The serialization circuit performs serial conversion of the input data in N-parallel manner and outputs bits in N-parallel manner, as a single serial output signal at timing corresponding to each phase. In synchronization with timing corresponding to each phase, the logical test circuit imports the serial output signal as N-parallel bit strings each having length equal to M/N number of bits and performs a bit logical test for M number of bits.

  • Patent number: 9989559
    Abstract: A test and measurement instrument includes a user interface and a controller. The controller is configured to receive a serial bit stream and apply a logic to the serial bit stream to identify states within the serial bit stream. The result of applying the logic to the serial bit stream is a combined state/bit stream. A regular expression can be applied to the combined state/bit stream: the regular expression can include state information. The controller is also configured to present output data through the user interface in response to the application of the regular expression to the combined state/bit stream.

  • Patent number: 9979585
    Abstract: Various embodiments are described of devices and associated methods for processing a signal using a plurality of vector signal analyzers (VSAs). An input signal may be split and provided to a plurality of VSAs, each of which may process a respective frequency band of the signal, where the respective frequency bands have regions of overlap. Each VSA may adjust the gain and phase of its respective signal such that continuity of phase and magnitude is preserved through the regions of overlap. The correction of gain and phase may be accomplished by a complex multiply with a complex calibration constant. A complex calibration constant may be determined for each VSA by comparing the gain and phase of one or more calibration tones generated with each region of overlap, as measured by each of the VSAs.

  • Patent number: 9961690
    Abstract: A method in a base station for selecting a transport format is provided. The base station allocates resources to a User Equipment, UE. When a first criterion is fulfilled for the allocated resources, the base station estimates Signal-to-Interference-plus-Noise Ratio, SINR, by using a first gain offset. The first gain offset relates to a resource allocation according to the first criterion. When a second criterion is fulfilled for the allocated resources, the base station estimates SINR by using a second gain offset. The second gain offset relates to a resource allocation according to the second criterion. The base station then selects a transport format for the allocated resources based on the estimated SINR.

  • Patent number: 9947401
    Abstract: Technology is described for keeping current (e.g., peak power supply current or ICC) in a non-volatile memory system within a target while maintaining high throughput. Programming conditions are adaptively changed at the sub-codeword level in order to keep power supply current of the memory system within a target. In one embodiment, a chunk of data that corresponds to a sub-codeword is written while consuming lower than normal programming current in order to keep power supply current within a target. The relatively low programming current may increase the expected raw BER. However, other portions of the codeword can be written with a higher than normal programming current, which results in a lower expected bit raw error rate for the memory cells that store that portion.

  • Patent number: 9935724
    Abstract: An emulator for modeling a network of K transmitters, L receivers, and M multipath components using a product distribution modeling system. The emulator determines for each of MLK paths defined between the transmitters and receivers respective delay, loss, and fading components. The fading component (e.g., attenuation-based, multipath, or both) is determined by calculating a weight value of a time-varying random variable type for each input impulse associated with the K transmitters and for each output impulse associated with the L receivers (including multipath). The modeling subsystem determines a signal propagation value for a modeled communication channel among the MLK paths by combining the delay component, the loss component, and the respective weight values of the input and output impulses associated with the modeled communication channel. The testing subsystem uses the signal propagation value to emulate the modeled communication channel using one or more computer processors.
