    Abstract: 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.

    Abstract: Methods and systems for cross-protocol time synchronization may comprise, for example, in a premises-based network, receiving a signal that conforms to a data over cable service interface specification (DOCSIS) communications protocol. A global time of day (GTOD) clock may be extracted from the received signal. Communication on the premises-based network in accordance with a multimedia over cable alliance (MoCA) communications protocol may be synchronized based at least in part on the extracted GTOD clock. Communication in a third communications protocol may be synchronized, wherein the third communications protocol may include a home phoneline networking alliance (HPNA) standard, an IEEE 802.11x standard, and a non-public wireless network protocol. The extracted GTOD clock may comprise a GPS clock, GLONASS clock, and a Galileo clock. A second signal for extracting a GTOD may be received, such as a satellite signal, and may conform to a low Earth orbit satellite signal protocol.

    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.

    Abstract: A network device may receive a signal from a headend, wherein a bandwidth of the received signal spans from a low frequency to a high frequency and encompasses a plurality of sub-bands. The network device may determine, based on communication with the headend, whether one of more of the sub-bands residing above a threshold frequency are available for carrying downstream data from the headend to the circuitry. The network device may digitize the signal using an ADC operating at a sampling frequency. The sampling frequency may be configured based on a result of the determining. When the sub-band(s) are available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively high frequency. When the sub-band(s) are not available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively low frequency.

    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 comprise a multimedia over cable alliance (MoCA) standard and the second communication protocol may comprise an IEEE 802.11x standard. The determining and routing may be performed by a MoCA network controller. The first communication protocol may comprise an IEEE 802.11x standard and the second communication protocol may comprise 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.
