    Abstract: A first Multimedia over Coax Alliance (MoCA) compatible device comprises a physical layer profiling circuit and a spectrum abstraction circuit. The physical layer profiling circuit may for example be operable to measure a performance metric for each of a plurality of subbands on a shared coaxial cable of a MoCA network. The spectrum abstraction circuit may for example be operable to select, based at least in part on the measured performance metric, a subset of the subbands to be used for communication over the coaxial cable between the first MoCA-compatible device and a second MoCA-compatible device. The spectrum abstraction circuit may for example be operable to receive an indication of whether channel bonding is to be used for the communication over the coaxial cable between the first MoCA-compatible device and the second MoCA-compatible device. The spectrum abstraction circuit may for example be operable to perform the selection of the subset of the subbands based at least in part on the indication of whether channel-bonding is to be used.

    Abstract: Methods and systems are provided for adaptive management of local networks, such as in-premises networks, which may have access to and/or may be connected to external networks, such cable or satellite networks. A network management device that manages a local network may receive from a client device in the local network, a communication request relating to communication within the local network, may process the communication request, and may configure the communication of the client device based on processing of the communication request. The processing of the communication request may include assessing effects of communication of the client device, at the network management device, on other connections and/or communications, with the other connections and/or communications including external connections and/or communications with one or more devices and/or networks external to the local network. Processing of the communication request may include assessing likelihood of interference at the network management device.

    Abstract: Systems and methods are provided for full duplex DOCSIS cable modem echo cancellation with training. During reception of downstream signals, echo effects on downstream signals may be determined, with at least some of the echo effects corresponding to concurrently transmitted upstream signals. Echo cancellation corrections may be determined based on the determined echo effects, and the echo cancellation corrections may be applied during processing of the downstream signals. The echo cancellation corrections may include one or both of ACI (adjacent channel interference) cancellation corrections and ALI (adjacent leakage interference) cancellation correction. The echo cancellation may include or be based on preforming echo cancellation training, during active communication and based on one or both of the downstream signals and the upstream signals.

    Abstract: Circuitry of a hybrid fiber-coaxial network may comprise a first transceiver configured to connect the circuitry to an optical link, a second transceiver configured to connect the circuitry to an electrical link, a first processing path, a second processing path, and a switching circuit. In a first configuration, the switching circuit may couple the first transceiver to the second transceiver via the first processing path. In a second configuration, the switching circuit may couple the first transceiver to the second transceiver via the second processing path. The first transceiver may comprise a passive optical network (PON) transceiver and the second transceiver may comprise a data over coaxial service interface specification (DOCSIS) physical layer transceiver. The switching circuit may be configured based on the type of headend to which the circuitry is connected.

    Abstract: A receiver includes a plurality of input paths for receiving and processing a plurality of input RF signals. The input paths isolate one or more portions of corresponding ones of the received input RF signals, and combine the isolated portions of the corresponding ones of the received input RF signals onto one or more output signals. A bandwidth of the isolated portions of the corresponding ones of the received input RF signals and a bandwidth of the output signals are variable. The isolated portions of the corresponding ones of the received plurality of input RF signals are extracted and utilized to generate the output signals. The portions of the corresponding ones of the received plurality of input RF signals may be mapped into one or more channel slots in the time domain. The channel slots may be assigned in the frequency domain to one or more frequency bins.

    Abstract: A cable modem termination system (CMTS) may communicate with a plurality of cable modems using a plurality of orthogonal frequency division multiplexed (OFDM) subcarriers. The CMTS may determine a performance metric of each of the cable modems. For each of the OFDM subcarriers and each of the cable modems, the CMTS may select physical layer parameters to be used for communication with that cable modem on that OFDM subcarrier based on a performance metric of that cable modem. The parameters may be selected for each individual modem and/or each individual subcarrier, or may be selected for groups of modems and/or groups of subcarriers. The parameters may include, for example, one or more of: transmit power, receive sensitivity, timeslot duration, modulation type, modulation order, forward error correction (FEC) type, and FEC code rate.
