Abstract:
Methods and systems are provided for guard band detection and/or frequency offset detection. For example, a signal processing circuit may be operable to determine, for each of a plurality of downconverted signals, one or more frequency offsets that are associated with one or more corresponding local oscillators (LOs) used in obtaining the plurality of downconverted signals; and relating to the determined frequency offsets may be generated for the plurality of downconverted signals. The signal processing circuit may perform, based on the generated information, one or both of a band stacking operation and a channel stacking operation so as to prevent channels/bands being stacked on each other or being overlapped.

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:
A system comprises a microwave backhaul outdoor unit having a first resonant circuit, phase error determination circuitry, and phase error compensation circuitry. The first resonant circuit is operable to generate a first signal characterized by a first amount of phase noise and a first amount of temperature stability. The phase error determination circuitry is operable to generate a phase error signal indicative of phase error between the first signal and a second signal, wherein the second signal is characterized by a second amount of phase noise that is greater than the first amount of phase noise, and the second signal is characterized by a second amount of temperature instability that is less than the first amount of temperature instability. The phase error compensation circuitry is operable to adjust the phase of a data signal based on the phase error signal, the adjustment resulting in a phase compensated signal.

Abstract:
One or more circuits for use in a transceiver that is collocated with a satellite dish, may receive a satellite signal carrying media content, and remove content protection from the received media content. After removing the first content protection, the one or more circuits may apply second content protection to the media content. The content protection applied by the one or more circuits may adhere to a different protocol, utilize different keys, and/or otherwise be distinguishable from the content protection that was removed. After applying the content protection, the one or more circuits may transmit the media content onto one or more links between the satellite dish and one or more client devices. The removal of the content protection may comprise descrambling and/or decrypting the media content. The application of the content protection may comprise scrambling and/or encrypting the media content.

Methods and systems are provided for band translation with protection. A signal processing circuitry (chip) may be configured to receive and process a plurality of input signals, and generate one or more output signals based on the plurality of input signals. The processing may comprise determining when including a component of a first input signal into at least one output signal would have an effect on a component of a second input signal that is also to be included in the output signal, and applying, based on the effect, one or more adjustments to processing of one or both of the first signal and the second signal to mitigate the effect before generating the output signal. In this regard, applying the one or more adjustments may comprise applying one or both of filtering and spectral inversion to one or both of the first signal and the second signal.
