  • Patent number: 11063696
    Abstract: Disclosed in some examples are methods, systems, devices, and machine-readable mediums which optimize one or more metrics of a communication system by intentionally changing symbols in a bitstream after encoding by, an error correction coder, but prior to transmission. The symbols may be changed to meet a communication metric optimization goal, such as decreasing a high PAPR, reducing an error rate, reducing an average power level (to save battery), or altering some other communication metric. The symbol that is intentionally changed is then detected by the receiver as an error and corrected by the receiver utilizing the error correction coding.

  • Patent number: 11022995
    Abstract: A client device manages consumption of power supplied by an electric utility to power consuming devices. Power flow to the power consuming devices is selectively enabled and disabled by one or more controllable devices controlled by the client device. The client device receives a power control message from a load management server. The power control message indicates at least one of an amount of electric power to be reduced and an identification of at least one controllable device to be instructed to disable a flow of electric power to one or more associated power consuming devices. Responsive to the power control message, the client device issues a power management command to one or more controllable devices under the client device's control. The power management command causes the one or more controllable devices to disable a flow of electric power to the one or more associated power consuming device.

    Abstract: The present disclosure discloses a method and a system for providing a code cover to Orthogonal Frequency Division Multiplexing (OFDM) symbols in a multiple user system. A data sequence is received from each of a plurality of users. Further, a reference sequence is generated for the data sequence of each of the plurality of users. Each of the reference sequence is multiplied with a code cover which are orthogonal to each other. Each of the reference sequence is time-multiplexed with corresponding data sequence, to generate a corresponding multiplexed sequence. Further, a Discrete Fourier Transform (DFT) is performed on each of the multiplexed sequence to generate a corresponding DFT-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) symbol. Lastly, the corresponding DFT-s-OFDM symbol is processed for transmitting over corresponding one or more channels.

  • Patent number: 10499148
    Abstract: A wireless microphone and/or in-ear monitoring system having a clock master prescribing a wordclock, and a clock slave to be synchronized to the wordclock. Between the clock master and the clock slave is a digital wireless transmission link which digitally transmits synchronization signals and audio signals. The clock master has a clock reference prescribing a first sample clock, and a first timer. A first phase of the first clock signal is detected after expiry of the first timer and is wirelessly transmitted to the clock slave, which has a second timer. After expiry of the second timer, a second phase of the second clock signal of the clock slave is detected and compared to the wirelessly transmitted first phase. The difference between the first and second phases is used as an input value as a control unit in the clock slave. The control unit adjusts an adjustable sample clock of the clock slave to correspond to the first clock.

  • Patent number: 10491266
    Abstract: In an ultra-wideband (“UWB”) receiver, a received UWB signal is periodically digitized as a series of ternary samples. During a carrier acquisition mode, the samples are continuously correlated with a predetermined preamble sequence to develop a correlation value. When the value exceeds a predetermined threshold, indicating that the preamble sequence is being received, estimates of the channel impulse response (“CIR”) are developed. When a start-of-frame delimiter (“SFD”) is detected, the best CIR estimate is provided to a channel matched filter (“CMF”). During a data recovery mode, the CMF filters channel-injected noise from the sample stream. Both carrier phase errors and data timing errors are continuously detected and corrected during both the carrier acquisition and data recovery modes of operation.

    Abstract: A client device manages consumption of power supplied by an electric utility to power consuming devices. Power flow to the power consuming devices is selectively enabled and disabled by one or more controllable devices controlled by the client device. The client device receives a power control message from a load management server. The power control message indicates at least one of an amount of electric power to be reduced and an identification of at least one controllable device to be instructed to disable a flow of electric power to one or more associated power consuming devices. Responsive to the power control message, the client device issues a power management command to one or more controllable devices under the client device's control. The power management command causes the one or more controllable devices to disable a flow of electric power to the one or more associated power consuming device.

The invention provides interference temperature-adaptive waveforms, and a variety of physical and media access control protocols for generating waveforms based on measurement and characterization of the local spectrum. The invention measures the local spectrum at a receiving node, generates an optimal waveform profile specifying transmission parameters that will water-fill unused spectrum up to an interference limit without causing harmful interference to primary and legacy transmitters using the same frequency bands, and enables simultaneous transmit and receive modes at a multiplicity of transceivers in a wireless network.
