    Abstract: Methods and systems for providing reduced bandwidth acquisition latency may comprise communicating a reservation request for bandwidth allocation for devices operating under a wired network protocol, where the reservation request may be sent by wired network devices via a wireless network protocol over a wireless network. Bandwidth may be allocated in the wired network for the requesting devices by a network controller. Data may be communicated with the requesting devices via the wired network. The wired network communication protocol may comprise a multimedia over cable alliance (MoCA) standard. The wireless protocol may comprise an IEEE 802.11x standard, a Bluetooth standard, and/or any non-public network protocol. The communication of the reservation request via the wireless protocol may decrease a latency of the wired network. A medium access plan (MAP) may be generated by the network controller based on the reservation request and may comprise a bandwidth allocation for the requesting devices.

    Abstract: A WiFi access point (AP) includes a receive radio frequency (RF) front end and a baseband processor that controls operation of the receive RF front end. The RF front end captures signals over a wide spectrum that includes a plurality of WiFi frequency bands (2.4 GHz and 5 GHz) and channelizes one or more WiFi channels from the captured signals. The baseband processor combines a plurality of blocks of WiFi channels to create one or more aggregated WiFi channels. The receive RF front end may be integrated on a first integrated circuit and the baseband processor may be integrated on a second integrated circuit. The first and second integrated circuits may be integrated on a single package. The RF front end and the baseband processor may be integrated on a single integrated circuit. The WiFi access point comprises a routing module that is communicatively coupled to the baseband processor.

    Abstract: Methods and systems for improved cross polarization rejection and tolerating of coupling between satellite signals may comprise receiving radio frequency (RF) signals on a chip, where the RF signals comprising a desired signal and at least one crosstalk signal. The received RF signals may be down-converted to baseband frequencies, and the down-converted signals are converted to digital signals. Crosstalk may be determined by estimating complex coupling coefficients between the received RF signals utilizing a de-correlation algorithm across a frequency bandwidth comprising the desired and crosstalk signals. The down-converted signals may be low-pass filtered and summed with an output signal from a cancellation filter. The complex coupling coefficients may be determined utilizing the de-correlation algorithm on the summed signals, and may be used to configure the cancellation filter. Crosstalk may be canceled in a receiver path from a cancellation filter receiving low-pass filtered down-converted signals from another path.

    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: 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: Aspects of methods and systems for transceiver array synchronization are provided. An array based communications system comprises a plurality of transceiver circuits and an array coordinator. Each transceiver circuit of the plurality of transceiver circuits comprises a plurality of wireless transmitters and a local oscillator generator. Each wireless transmitter of the plurality of wireless transmitters is able to modulate a local oscillator signal from the local oscillator generator based on a weighted sum of a plurality of digital datastreams. The array coordinator is able to adjust a phase of a first local oscillator signal based on a phase difference between the first local oscillator signal and a second local oscillator signal. The first local oscillator signal is generated by a first local oscillator generator of a first transceiver circuit. The second local oscillator signal is generated by a second local oscillator generator of a second transceiver circuit.
