Abstract: A receiver includes a static I/Q calibration block and a correlation/integration block. The static I/Q calibration block is configured to substantially eliminate mismatches between in-phase and quadrature components of a portion of the spectrum having associated I/Q mismatches that are relatively frequency-independent. The correlation/integration block is configured to substantially eliminate mismatches between the in-phase and quadrature components of portions of the spectrum having associated I/Q mismatches that are relatively frequency-dependent in accordance with a pair of signals generated by the static I/C calibration block.

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: A method and apparatus for memory power and/or area reduction. An array of memory cells may be scanned to detect faulty memory cells, if any, in the array. A supply voltage Vmem applied to the array of memory cells may be controlled based on a result of the scan, and based on a sensitivity coefficient of one, or more, of the array of memory cells. The sensitivity coefficient may indicate an impact that the one, or more, of the array of memory cells being faulty may have on the performance of a device that reads and writes data to the memory array. Additionally or alternatively, the physical dimensions of the memory cells may be determined based on the sensitivity coefficient(s) and/or based on a number of faulty memory cells that can be tolerated in the array of memory cells.

A second radiation pattern of the plurality of antenna elements may correspond to a second microwave backhaul link between the first microwave transceiver and a third microwave backhaul transceiver. The transceiver may adjust the radiation pattern based on characteristics of data to be transmitted, and based on a routing table it maintains.

Abstract: An Internet protocol low noise block downconverter (IP LNB), which may be within a satellite reception assembly, may be operable to determine location information and time information of the IP LNB, and may communicate the determined location information and the corresponding time information to a wireless communication device communicatively coupled to the IP LNB. The communicated location information may be configured to enable the wireless communication device to determine its location based on the determined location information and the corresponding time information. The IP LNB may determine the location information and/or the time information of the IP LNB based on global navigation satellite system (GNSS) signals, which may be received via the satellite reception assembly and may be processed via the IP LNB. The IP LNB may provide services based on the determined location information and/or the determined time information of the IP LNB.
