  • Patent number: 10135638
    Abstract: Generally, the described techniques provide for protection mechanisms for sounding training signals transmitted between wireless devices when performing ranging sounding estimation. For example, sounding training signals may be encoded to include a sequence of phase rotations or cyclic shifts to protect the sounding training signal from peer devices. In some cases, encoding information associated with a long training field (LTF) may be transmitted either before or after the LTF is transmitted. Additionally or alternatively, a time delay may be introduced to the sounding training signal, where timing information may be removed from one or more fields of the sounding training signal and the time delay may be appended to an interframe spacing. Alternatively, a frame may be split into multiple frames with the sounding training signal in a first frame, and timing information in a second frame that is offset in time from the first frame.

  • Patent number: 10128664
    Abstract: An electrical power distribution system comprises recloser monitors that monitor power line voltages to thereby whether reclosers are open or closed. The recloser monitors report the voltages and associated times to a remote recipient, such as by cell phone. Momentary voltage drops that do not result in a power outage are reported as well. At least some of the recloser monitors are carried by power poles and desirably comprise weather stations for reporting localized weather conditions. The overall efficiency and reliability of the power distribution system is improved by allowing for more rapid identification of outage locations and proactive repair of power system components prior to actual outages.

  • Patent number: 10110287
    Abstract: A transmitter generates precoding matrices for communication channels of a transmitter, The transmitter includes a plurality of user-specific channels, with each user specific channel associated with a different set of user equipment (UE) receive antennas. For precoding, the transmitter generates a baseline channel matrix reflecting the characteristics of the communication medium employed to transmit data to the different user equipment (UEs). For each user-specific channel, the transmitter generates a set of null space vectors wherein only a subset of the generated null space vectors generated by the transmitter are used to precode the data. To identify the combination of null space vectors to be used for each channel, the transmitter calculates a quality score for each such combination of null space vectors. The transmitter uses the subset of null vectors that yields the highest score to precode the data.

  • Patent number: 10075286
    Abstract: Disclosed is a mechanism for limiting Intersymbol Interference (ISI) when measuring uncorrelated jitter in a test and measurement system. A waveform is obtained that describes a signal. Such waveform may be obtained from memory. A processor then extracts a signal pulse from the waveform. The processor selects a window function based on a shape of the signal pulse. Further, the processor applies the window function to the signal pulse to remove ISI outside a window of the window function while measuring waveform jitter. The window function may be applied by applying the window function to the signal pulse to obtain a target pulse. A linear equalizer is then generated that results in the target pulse when convolved with the signal pulse. The linear equalizer is then applied to the waveform to limit ISI for jitter measurement.
