    Abstract: A DC offset removal method and apparatus for use with a receiver, such as a direct conversion receiver. The DC offset error can be upconverted to an intermediate frequency where it appears as a DC offset spurious signal. The DC offset spurious signal can be amplified and downconverted back to a DC signal. The DC signal can be used to determine an offset correction value that can be coupled to a signal path to substantially remove the DC offset error. An embodiment is disclosed that allows a single module to be used to remove the static and dynamic DC offset error components. Another embodiment includes separate portions for the removal of static and dynamic offset errors.

    Abstract: A radio integrated circuit includes, in part, an analog front end block, an analog-to-digital converter responsive to the analog-front end block, a digital signal processor responsive to the analog-to-digital converter and adapted to generate in-phase and quadrature signals, and a serial communication interface configured to receive and transmit the in-phase and quadrature signals. The serial communication interface supplies a gain control signal to the analog front end block when a switch disposed in the radio integrated circuit is in a first position. When the switch is in a second position, a gain control block disposed in the radio integrated circuit receives a gain control signal from the analog-to-digital converter and supplies the gain control signal to the analog front end block. The digital signal processor may be configured to interleave the in-phase and quadrature signals.

    Abstract: A first device of a multimedia over coax alliance (MoCA) network may grant a second device of the MoCA network permission to enter a power-saving state. While the second device is in the power-saving mode, the first device may grant bandwidth to the second device during one or more predetermined timeslots. The bandwidth may be granted without a corresponding reservation request from the second device. While the second device is in the power-saving state, it may track time utilizing a clock that is synchronized to the system time of the MoCA network, and transmit during one or more of the predetermined timeslots without first transmitting a corresponding reservation request. The second device may utilize a first modulation profile when not operating in the power-saving state, and utilize a second modulation profile when operating in the power-saving state.

    Abstract: 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.

    Abstract: An automatic gain control loop disposed in a receiver is adapted to compensate for varying levels of out of band interference sources by adaptively controlling the gain distribution throughout the receive signal path. One or more intermediate received signal strength indicator (RSSI) detectors are used to determine a corresponding intermediate signal level. The output of each RSSI detector is coupled to an associated comparator that compares the intermediate RSSI value against a corresponding threshold. The take over point (TOP) for gain stages is adjusted based in part on the comparator output values. The TOP for each of a plurality of gain stages may be adjusted in discrete steps or continuously.
