摘要： A first device of a Multimedia Over Coax Alliance (MoCA) network may communicate with a second device of the MoCA network to control power-save operation of the second MoCA device. The first device may control the power-save operation of the second MoCA device based on an amount of data stored in a buffer, wherein the data stored in the buffer is destined for the second device. The buffer may be in a third device which sends the data to the second device, and/or the buffer may be in the first device. The first device may be operable to buffer data destined for the second device while the second device is in a power-saving state.

摘要： An array based communications system may comprise a plurality of element processors. Each element processor may comprise a combining circuit, a crest factor circuit, and a phase shifter circuit. The combining circuit may produce a weighted sum of a plurality of digital datastreams. The crest factor circuit may be operable to determine whether the weighted sum has a power above or below a power threshold. If the power is above the power threshold, the crest factor circuit is operable to reduce the power. If the power is below the power threshold, the crest factor circuit is operable to increase the power. The phase shifter circuit may introduce a phase shift to out-of-band components of the weighted sum according to the power increase or the power decrease by the crest factor circuit.

摘要： Methods and systems for interference avoidance in a multi-protocol communication system may comprise receiving signals in a first communications protocol in a first frequency range and preventing interference signals from being generated in said first frequency range by configuring channel usage in a second communications protocol in a second frequency range based on said received signals. The configuring channel usage may include avoiding communicating in taboo channels and the received signals in said first communications protocol and signals in said configured channels in said second communications protocol may be communicated over one or more coaxial cables based on the configured channel usage. The taboo channels may be selected based on said received signals such that interference signals from said second frequency range do not occur in said first frequency range. The first frequency range comprises a cable or satellite television frequency range, or data over cable service interface standard (DOCSIS).

摘要： A cable modem termination system (CMTS) may determine, for a cable modem served by the CMTS, a SNR-related metric. The CMTS may assign the modem among a plurality of service groups based on the SNR-related metric. The CMTS may configure physical layer communication parameters to be used by the modem based on a SNR-related metric of a service group to which the modem is assigned. The physical layer communication parameters may include one or more of: transmit power, receive sensitivity, timeslot duration, modulation type, modulation order, forward error correction (FEC) type, and FEC code rate. The CMTS and the modem may communicate using orthogonal frequency division multiplexing (OFDM) over a plurality of subcarriers, and the physical layer communication parameters may be determined on a per-subcarrier basis.

摘要： Methods and apparatus for processing multichannel signals in a multichannel receiver are described. In one implementation, a plurality of demodulators may provide a plurality of outputs to a processor, with the processor then simultaneously estimating noise characteristics based on the plurality of outputs and generating a common noise estimate based on the plurality of outputs. This common noise estimate may then be provided back to the demodulators and used to adjust the demodulation of signals in the plurality of demodulators to improve phase noise performance.

摘要： Nonlinearity correction in a device that performs analog-to-digital conversion on received analog signals, may be calibrated by generating correction-parameters estimation which when applied to the total spectral content reduces distortion resulting from said nonlinearity in originally-unoccupied spectral regions. Digital signals generated based on sampling of the received analog signals may then be corrected, to remove nonlinearity related distortion, based on the estimated correction-parameters. The nonlinearity calibration may be performed during reception and handling of said analog signals. The correction-parameters may be generated based on signals located in particular spectral regions, such as the originally-unoccupied spectral regions. These signals may be injected within the device, into the particular spectral regions, and the signal may have known characteristics to enable estimating the required correction.

摘要： Methods and systems for time interleaved analog-to-digital converter timing mismatch calibration and compensation may include receiving an analog signal on a chip, converting the analog signal to a digital signal utilizing a time interleaved analog-to-digital-converter (ADC), and reducing a blocker signal that is generated by timing offsets in the time interleaved ADC by estimating complex coupling coefficients between a desired digital output signal and the blocker signal utilizing a decorrelation algorithm on frequencies within a desired frequency bandwidth. The decorrelation algorithm may comprise a symmetric adaptive decorrelation algorithm. The received analog signal may be generated by a calibration tone generator on the chip. An aliased signal may be summed with an output signal from a multiplier. The complex coupling coefficients may be determined utilizing the decorrelation algorithm on the summed signals. A multiplier may be configured to cancel the blocker signal utilizing the determined complex coupling coefficients.
