Abstract: Aspects of a method and system for data converters having a transfer function with multiple operating zones. In some embodiments, an operating zone of the multiple operating zones is characterized by more stringent performance criteria than the other operating zones. Thus, such data converters may receive an input signal and generate an output signal from the input signal per the transfer function and the more stringent performance criteria in the appropriate operating zone.

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.

Abstract: A cable modem termination system (CMTS) may determine, for a plurality of cable modems served by the CMTS, a corresponding plurality of SNR-related metrics. The CMTS may assigning the modems among a plurality of service groups based on the SNR-related metrics. For any one of the modems, the CMTS may configure physical layer communication parameters to be used by the one of the modems based on a SNR-related metric of a service group to which the one of the modems is assigned. The physical layer communication parameters may include one or more of: transmit power, receive sensitivity, timeslot duration, modulation type, modulation order, forward error correction (FEC) type, and FEC code rate. The CMTS and the modems may communicate using orthogonal frequency division multiplexing (OFDM) over a plurality of subcarriers, and the physical layer communication parameters may be determined on a per-subcarrier basis.

Abstract: A terrestrial receiver at a premises includes a plurality of antennas and a corresponding plurality of tuners. The terrestrial receiver receives terrestrial television signals via the plurality of antennas and the plurality of tuners and diversity combines a corresponding plurality of terrestrial television channels within the received terrestrial television signals, for example, based on control signals received from one or more customer premises equipment (CPE). The terrestrial receiver processes the diversity combined corresponding plurality of terrestrial television channels and communicates the processed and diversity combined corresponding plurality of terrestrial television channels to the one or more CPE. The diversity combined corresponding plurality of terrestrial television channels may be remodulated, and converted to corresponding analog signals prior to being communicated to the one or more CPE. The diversity combined corresponding plurality of terrestrial television channels may be demodulated and converted to intermediate frequency signals prior to being communicated to the one or more CPE.

Abstract: A direct broadcast satellite (DBS) reception assembly may receive a desired satellite signal and process the desired satellite signal for output to a gateway. The DBS assembly may also receive one or more undesired satellite signals and determine a performance metric of the one or more undesired satellite signals. The elevation angle of the assembly and/or the azimuth angle of the assembly may be adjusted based on the performance metric(s) of the undesired satellite signal(s). The adjusting of the elevation angle and/or the azimuth angle may comprise electronically steering a directivity of a receive radiation pattern of the DBS reception assembly and/or mechanically steering one or more components of the assembly via motors, servos, actuators, MEMS, and/or the like. The performance metric may be received signal strength of the undesired signals, received signal strength of the desired signal, SNR of the desired signal, and/or SNR of the undesired signals.

The first mobile consumer electronic device may process the captured signal to determine which of the multiple frequency bands are not currently in use by other devices. The first mobile consumer electronic device may select a plurality of the frequency bands. The first mobile consumer electronic device may transmit, via the BNC transceiver, a signal over the selected plurality of frequency bands at a determined strength, where the signal carries video data destined for the second mobile consumer electronic device.

Abstract: Nonlinearity correction in a device that performs analog-to-digital conversion on received analog signals, may be calibrated by generating correction-parameters estimation which when applied to the total spectral content reduces distortion resulting from said nonlinearity in originally-unoccupied spectral regions. Digital signals generated based on sampling of the received analog signals may then be corrected, to remove nonlinearity related distortion, based on the estimated correction-parameters. The nonlinearity calibration may be performed during reception and handling of said analog signals. The correction-parameters may be generated based on signals located in particular spectral regions, such as the originally-unoccupied spectral regions. These signals may be injected within the device, into the particular spectral regions, and the signal may have known characteristics to enable estimating the required correction.

Abstract: Methods and systems are provided for hot-swappable hardware for communication links (e.g., wireless microwave links). A communication assembly that comprises processing circuitry may be configured to allow replacing a circuitry element during active operation of the communication assembly. The replacing may comprise configuring the communication assembly to communicate signals based on a first configuration, using the circuitry element being replaced; receiving addition of a replacement circuitry element; configuring the communication assembly to communicate signals based on a second configuration, using the replacement circuitry element; and after the communication assembly is fully configured to communicate signals based on the second configuration, removing the circuitry element being replaced.
