    摘要： A transceiver system may be configured to provide tunable bandwidths. The transceiver may comprise a signal processing component and a filtering component, which may comprise a plurality of filters. The signal processing component may determine one or more adjustments that are applicable to one or both of a first filter that is configured for filtering signals corresponding to a first frequency band associated with a first stream, and a second filter that is configured for filtering signals corresponding to a second frequency band associated with a second stream. The one or more adjustments may correspond to modifications in one or both of the first frequency band and the second frequency band. The one or more adjustments may be communicated to the filtering component, which may apply the adjustments to one or more of the plurality of filters.

    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： 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.
