摘要： Methods and apparatus for processing multichannel signals in a multichannel receiver are described. In one implementation, a plurality of demodulator circuits may provide a plurality of outputs to a processing module, with the processing module then simultaneously estimating noise characteristics based on the plurality of outputs and generating a common noise estimate based on the plurality of outputs.

摘要： 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.

摘要： A CMTS may receive a request that a network device be permitted to enter a power-saving mode of operation. In response, the CMTS may enter a power-saving mode of operation wherein MAC management messages, transmission opportunities for the sleeping network device, and/or contention periods on one or more channels occur at independently determinable intervals. The CMTS may then transmit a message granting the network device permission to enter the power-saving mode of operation. The CMTS may start a sleep timer upon transmitting the MAC management message and may deregister the network device if no communication is received from the network device prior to expiration of the sleep timer. The CMTs may buffer traffic destined for the network device in a buffer of the CMTS while the network device is in the power-saving mode of operation, and may wake the network device upon the amount of buffered traffic reaching a threshold.

摘要： A WiFi device, which utilizes full spectrum capture, captures signals over a wide spectrum including one or more WiFi frequency bands and extracts one or more WiFi channels from the captured signals. The AP analyzes the extracted WiFi channels and aggregates a plurality of blocks of WiFi channels to create one or more aggregated WiFi channels based on the analysis. The WiFi frequency bands comprise 2.4 GHz and 5 GHz WiFi frequency bands. The AP determines one or more characteristics of the extracted WiFi channels based on the analysis. The determined characteristics comprise noise, interference, fading and blocker information. The AP generates a channel map comprising at least the extracted one or more WiFi channels based on the determined characteristics. The AP dynamically and/or adaptively senses the extracted one or more WiFi channels and updates the determined characteristics of the extracted WiFi channels.

摘要： A wireless communication device (WCD) generates and transmits wireless broadband signals (WBS) at a power level that is below a spurious emissions mask such that the transmitted WBS occupy a designated frequency spectrum band. The WCD transmits duty cycle bursts of the WBS and determines range, position and/or movement based on the transmitted burst of the WBS. A bandwidth of the wireless broadband signals may occupy approximately 800 MHz within a range of 0 Hz to 1 GHz. The transmit power utilized for transmitting the WBS may be spread over a bandwidth of approximately 300 MHz within the 800 MHz bandwidth. The spreading results in a power spectral density of the transmitted WBS approximating thermal noise at a distance of approximately 3 meters. A course range may be determined utilizing wireless signals other than the transmitted bursts and a fine range may be determined utilizing the transmitted bursts.
