    Abstract: Methods and systems for cross-protocol time synchronization may comprise, for example, in a premises-based network: receiving, by a network controller located at a root node in the premises, signals that conform to one or more first communications protocol; bridging said received signals to conform to a second communications protocol different from the one or more first communications protocol; and communicating said bridged signals to one or more networked devices within said premises-based wired network, wherein only signals conforming to said second communications protocol are concurrently communicated in a frequency range that is independent of frequency range limitations of the one or more first communications protocol and of the second communications protocol, and that is limited only by a frequency range of wiring in the premises-based network. One of the signals conforming to the one or more first communications protocol comprises a data over cable service interface specification (DOCSIS) signal.

    Abstract: Methods and systems for optimizing bandwidth utilization in an in-home network may comprise determining usage and/or quality of communication links operating in accordance with first and second communication protocols in a multi-protocol wired and wireless network. Data communication may be routed from a first communication link operating in accordance with the first communication protocol to a second communication link operating in accordance with the second communication protocol, based on the determining. The first communication protocol may include a multimedia over cable alliance (MoCA) standard and the second communication protocol may include an IEEE 802.11x standard. The determining and routing may be performed by a MoCA network controller. The first communication protocol may include an IEEE 802.11x standard and the second communication protocol may include a MoCA standard. The rerouting may increase bandwidth usage efficiency and/or data throughput of the network. The determining and rerouting may be performed dynamically.

    Abstract: Systems and methods are provided for adaptive control of pre-distortion during signal transmissions. While applying pre-distortion during processing of an input signal for transmission, feedback data may be generated based on a plurality of feedback signals, and adjustments to the pre-distortion may be applied to the pre-distortion based on the feedback data. Each of feedback signals corresponds to a particular processing stage performed during the processing of the input signal. Generating the feedback data comprises applying adjustments to the plurality of feedback signals based on a type and/or a source of at least one feedback signal, with the adjustments comprising one or more of: applying a gain to one of the plurality of feedback signals; applying a delay to one of the plurality of feedback signals; and modifying a first one of the plurality of feedback signals based on a second one of the plurality of feedback signals.

    Abstract: Methods and systems for crest factor reduction may comprise generating an original waveform, generating a distortion signal by reducing a crest factor of the original waveform, generating an error signal by subtracting out the original waveform from the distortion signal, and generating a conditioned waveform by adding the error signal to the original waveform. The crest factor of the original waveform may be reduced based on spectral mask requirements. The crest factor of the original waveform may be reduced using a limiter. The power amplifier may comprise a programmable gain amplifier (PGA). The distortion signal may be generated based on a PGA model and/or a predistortion model. A signal from an output of the PA may be fed back to the PGA model. The PGA model may be dynamically configured. The crest factor of the original waveform may be reduced in an analog domain and/or a digital domain.

    Abstract: Circuitry for use in a network controller comprises a processor and memory. The network controller is operable to control communications in a network comprising a plurality of devices connected via a shared coaxial cable. The circuitry is operable to maintain one or more data structures that hold per-sender-receiver-pair link parameters and per-sender-receiver-pair bandwidth grant status. The circuitry is operable to, in response to receipt of a reservation request on the shared coaxial cable, decide which one or more of a plurality of subbands and which one or more of a plurality timeslots to reserve for the transmission based, at least in part, on the per-sender-receiver-pair link parameters and the per-sender-receiver-pair bandwidth grant status in the one or more data structures. The circuitry is operable to generate a reservation grant message that indicates the decided one or more subbands and the decided one or more timeslots.
