Abstract:
A satellite reception assembly that provides satellite television and/or radio service to a customer premises may comprise a wireless interface via which it can communicate with other satellite reception assemblies. Wireless connections between satellite reception assemblies may be utilized for providing satellite content between different satellite customer premises. Wireless connections between satellite reception assemblies may be utilized for offloading traffic from other network connections.

Abstract:
Methods and systems for multi-path video and network channels may comprise a communication device comprising a wideband path (WB) and a narrowband path (NB), wherein the WB may be operable to receive a plurality of channels and the NB may be operable to receive a single channel. Video channels and a network channel may be received in the WB when the device is operating in a first stage. Video channels and a network channel may be received in the WB and the network channel may also be received in the NB when the device is operating in a second stage. The network channel may be received in the NB when the device is operating in a third stage. The reception of the network channel from both the WB and the NB may enable a continuous reception of the network channel in a transition between the first and third stages.
Abstract:
Receiver architectures and methods of processing harmonic rich input signals employing harmonic suppression mixers are disclosed herein. The disclosed receivers, mixers, and methods enable a receiver to achieve the advantages of switching mixers while greatly reducing the mixer response to the undesired harmonics. A harmonic mixer can include a plurality of mixers coupled to an input signal. A plurality of phases of a local oscillator signal can be generated from a single local oscillator output. Each of the phases can be used to drive an input of one of the mixers. The mixer outputs can be combined to generate a frequency converted output that has harmonic rejection.

A communication receiver which applies signal processing for quantitatively estimating receive signal factors such as communication channel quality, signal characteristics, and overall system received bit error rate (BER) or packet error rate (PER) and which applies a general algorithm for mapping these estimated factors to control receiver performance and minimize power consumption.
Abstract:
A network device may be operable to receive an indication from a cable modem termination system (CMTS) that media access control (MAC) management messages will be transmitted by the CMTS at fixed intervals. Subsequent to receiving the indication, the network device may be operable to power down one or more components of the network device and set a sleep timer to a value equal to an integer multiple of the fixed interval minus a transition period. The network device may power up the one or more components of the network device upon expiration of the sleep timer. The network device may power up the one or more components of the network device upon an amount of traffic in a buffer of the network device reaching a threshold.
Abstract:
One or more circuits may include an array of memory cells corresponding to a particular memory address. The one or more circuits may be operable to discover a location of a faulty memory cell in the array of memory cells. The one or more circuits may be operable to arrange the order in which the bits of a data block are stored to said array of memory cells based, at least in part, on said discovered location of said faulty memory cell.
Abstract:
A satellite reception assembly may receive signals on a block of frequencies that encompasses channels of one or more wireless networks. The satellite reception assembly may convey information about signals received on the block of frequencies to a centralized location which may utilize the information to determine characteristics, such as coverage area and/or usage, of the wireless network(s). Additionally or alternatively, such information from a plurality of satellite reception assemblies may be aggregated and made available to third parties which may use the aggregate information, in combination with knowledge about the wireless network(s), to determine characteristics of the wireless network(s).
Abstract:
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.
Abstract:
A communication system may include a first broadband device and a second broadband device. Signals may be wirelessly communicated from the first broadband device to the second broadband device at a power level that is below a spurious emissions mask. The communicated signals may be transmitted over a designated frequency band. A barrier separates the first broadband device from the second broadband device. The first broadband device may be paired with the second broadband device, and the signals may be wirelessly communicated from the first to the second broadband device. The signals may be communicated using signal emitting/receiving components, which may be jointly configured to optimize near-field communication while nullifying or substantially reducing signaling in other ranges, particularly far-field or intermediate-field ranges. The signal emitting/receiving components may comprise dipole or coil antennas, with the desired optimization and nullification being achieved based on controlling of electromagnetic fields.
