    Abstract: Methods and systems are provided for adaptive management of local networks (e.g., in-premises networks, which may access or be connected to cable or satellite networks). A network device (e.g., a gateway device) may be configured to function as a network manager in a local network, to manage internal connections and/or communications within the local network. The managing may comprise assessing effects of the internal connections and/or communications on external connections and/or communications with one or more devices and/or networks external the local network; and setting and/or adjusting based on the assessed effects, one or more communication parameters associated with each one of the internal connections and/or communications. The effects of the internal connections and/or communications may result from utilizing one or more physical mediums that are shared with and/or are commonly used by the external connections and/or communications with one or more devices and/or networks external the local network.

    Abstract: Methods and systems for improved cross polarization rejection and tolerating of coupling between satellite signals may comprise receiving radio frequency (RF) signals on a chip, where the RF signals comprising a desired signal and at least one crosstalk signal. The received RF signals may be down-converted to baseband frequencies, and the down-converted signals are converted to digital signals. Crosstalk may be determined by estimating complex coupling coefficients between the received RF signals utilizing a de-correlation algorithm across a frequency bandwidth comprising the desired and crosstalk signals. The down-converted signals may be low-pass filtered and summed with an output signal from a cancellation filter. The complex coupling coefficients may be determined utilizing the de-correlation algorithm on the summed signals, and may be used to configure the cancellation filter. Crosstalk may be canceled in a receiver path from a cancellation filter receiving low-pass filtered down-converted signals from another path.

    Abstract: A direct broadcast satellite (DBS) reception assembly may receive a desired satellite signal and process the desired satellite signal for output to a gateway. The DBS assembly may also receive one or more undesired satellite signals and determine a performance metric of the one or more undesired satellite signals. The elevation angle of the assembly and/or the azimuth angle of the assembly may be adjusted based on the performance metric(s) of the undesired satellite signal(s). The adjusting of the elevation angle and/or the azimuth angle may comprise electronically steering a directivity of a receive radiation pattern of the DBS reception assembly and/or mechanically steering one or more components of the assembly via motors, servos, actuators, MEMS, and/or the like. The performance metric may be received signal strength of the undesired signals, received signal strength of the desired signal, SNR of the desired signal, and/or SNR of the undesired signals.

    Abstract: Methods and systems are provided for guard band detection and frequency offset detection. For each of a plurality of downconverted signals, frequency related information associated with one or more corresponding circuits used in obtaining the plurality of downconverted signals may be determined; and based on the determined frequency related information, one or both of a band stacking operation and a channel stacking operation may be performed. During the band stacking operation, frequency bands are not stacked on each other or stacked frequency bands do not overlap. During the channel stacking operation, channels are not stacked on each other or stacked channels do not overlap. The frequency related information may be determined based on predefined frequency related parameters associated with the corresponding circuits. Frequency corrections may be performed, on output signals corresponding to the band stacking operation and/or the channel stacking operation, based on the frequency related information.
