摘要： Methods and systems for providing satellite television service to a premises may comprise receiving satellite television signals utilizing a satellite dish, converting received satellite signals to internet protocol (IP) signals, and wirelessly communicating the IP signals into a premises to which the satellite dish corresponds. The IP signals may, for example, conform to a multimedia over cable alliance (MoCA) standard or a IEEE 802.11x standard. The wirelessly communicating may comprise magnetic coupling. The received satellite signals may, for example, be converted to IP signals utilizing an IP low-noise block downconverter (IP-LNB) which may comprise full-band capture receivers. The wireless communication of the IP signals may, for example, be within a wireless network of the dwelling or may be independent of a wireless network of the dwelling. The wirelessly communicated IP signals may be beam-formed and may be communicated wirelessly over one or more industrial, scientific, and medical (ISM) bands.

摘要： A wideband receiver system is provided to concurrently receive multiple RF channels including a number of desired channels that are located in non-contiguous portions of a radio frequency spectrum and to group the number of desired channels into a contiguous frequency band. The system includes a wideband receiver having a complex mixer for down-shifting the multiple RF channels and transforming them to an in-phase signal and a quadrature signal in the baseband. The system further includes a wideband analog-to-digital converter module that digitizes the in-phase and quadrature signals and a digital frontend module that transforms the digital in-phase and quadrature signals to baseband signals that contains only the number of desired RF channels. that are now located in a contiguous frequency band. An up-converter module up-shifts the baseband signals to a contiguous band in an IF spectrum so that the system can directly interface with commercially available demodulators.

摘要： A cable modem (CM) device captures signals over a wide spectrum including one or more cable frequency bands and sub-bands, and extracts one or more cable channels from the captured signals. The CM device is operable to analyze the extracted one or more cable channels and assigns a portion of the extracted one or more cable channels for upstream and/or downstream communication based on the analysis. The CM device may recapture one or more previously unused cable channels to be utilized for the upstream and/or downstream communication based on the analysis. The CM device may determine noise, interference and/or blocker information corresponding to the extracted one or more cable channels based on the analysis. Based on the determined noise, interference and/or blocker information, the cable modem termination system (CMTS) may assign or block usage of one or more cable channels for the upstream and/or downstream communication.
