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 mobile communication device includes, in part, a first wireless receiver adapted to determine, as it travels along a path, a multitude of positions of the mobile communication device using signals received from a primary positioning source, a second wireless receiver adapted to receive signals from one or more ambient wireless sources as the mobile communication device travels along the path, and a positioning module. An internal or external memory stores estimated positions and corresponding time references of the signals of the one or more ambient sources. The positioning module uses the data stored in the database to estimate the position of the mobile communication device when no primary positioning source signal is available. The positioning module optionally uses the data stored in the database to improve estimates of the position of the mobile communication device when primary positioning signal is available.

摘要： A system for processing signals may be configured to apply digital conversion to analog signals, and to apply, prior to the analog-to-digital conversion, a gain to at least a portion of the analog signals. The gain may be controlled and/or adjusted based on processing of digital output generated based on the analog-to-digital conversion. The system may comprise a plurality of sampling slices, which may be configured to provide the analog-to-digital conversion in interleaved (e.g., time-interleaved) manner. Each of the sampling slices may comprise a dedicated gain element, for applying gain to signals handled by the corresponding slice. The gain applied by the gain elements of the sampling slices may be controlled, independently, collectively, and/or in based on grouping into subsets. The gain may be controlled based on application of a particular gain control algorithm, which may be selected from a plurality of predefined algorithms.

摘要： Aspects of a method and apparatus for communicating electronic service guide information in a satellite television system are provided. A satellite communication system may receive a signal via an interface to a satellite dish, and receive data from a network via a second interface (e.g., an interface to a LAN or a WAN, such as the Internet). The satellite communication system may be operable to channelize the received satellite signal into a plurality of channels, wherein a first channel of the plurality of channels carries electronic service guide (ESG) data. The satellite communication system may select which of the plurality of channels to input to a demodulator based, at least in part, on whether ESG data is available via the second interface. A second channel carrying media data may be input to the demodulator while the ESG data is available via the second interface.

摘要： To determine the level of frequency drift of a crystal oscillator as a result of a change in the its temperature, the temperature of the crystal oscillator is sensed and used together with previously stored data that includes a multitude of drift values of the frequency of the crystal oscillator each associated with a temperature of the crystal oscillator. Optionally, upon initialization of a GPS receiver in which the crystal oscillator is disposed, an initial temperature of the crystal oscillator is measured and a PLL is set to an initial frequency in association with the initial temperature. When acquisition fails in a region, the ppm region is changed. The temperature of the crystal oscillator is periodically measured and compared with the initial temperature, and the acquisition process is reset if there is a significant change in temperature. The GPS processor enters the tracking phase when acquisition is successful.

摘要： A GNSS system operates intermittently and has adaptive activity and sleep time in order to reduce power consumption. The GNSS system provides an enhanced estimate of its position in the absence of GNSS signals of sufficient strength. The user's activity and behavior is modeled and used to improve performance, response time, and power consumption of the GNSS system. The user model is based, in part, on the received GNSS signals, a history of the user's positions, velocity, time, and inputs from other sensors disposed in the GNSS system, as well as data related to the network. During each activity time, the GNSS receiver performs either tracking, or acquisition followed by tracking. The GNSS receiver supports both normal acquisition as well as low-power acquisition.
