摘要： Methods and systems are provided for guard band detection and frequency offset detection. For each of a plurality of downconverted signals, frequency related information associated with one or more corresponding circuits used in obtaining the plurality of downconverted signals may be determined; and based on the determined frequency related information, one or both of a band stacking operation and a channel stacking operation may be performed. During the band stacking operation, frequency bands are not stacked on each other or stacked frequency bands do not overlap. During the channel stacking operation, channels are not stacked on each other or stacked channels do not overlap. The frequency related information may be determined based on predefined frequency related parameters associated with the corresponding circuits. Frequency corrections may be performed, on output signals corresponding to the band stacking operation and/or the channel stacking operation, based on the frequency related information.

摘要： Method and systems are provided for controlling adjustments of reception functions. Communication links may be setup between a transmitter and a receiver along with sideband control channels. Conditions and/or parameters, affecting estimated performance of reception, via the communication links, at the receiver, may then be monitored at the transmit-side, and information relating to the monitored conditions may then be communicated, via the sideband control channels, to enable adjusting reception related functions at the receiver. The reception related functions comprise analog-to-digital conversion, which may be configured to function in an interleaved manner.

摘要： Methods and systems are provided for band translation with protection. A signal processing circuitry (chip) may be configured to handle a plurality of signals, comprising at least a first signal corresponding to internal communication within an in-premises network and at least a second signal originating from a source external to the in-premises network; and to process on-chip the plurality of input signals, to generate one or more output signals. In this regard, at least one output signal may comprise components corresponding to the first signal and the second signal; and the processing may be configured to mitigate on-chip, during generating of the one or more outputs, at least one effect of including in the at least one output signal a first component corresponding to one of the first signal and the second signal on a second component corresponding to the other one of the first signal and the second signal.

摘要： A microwave backhaul system may comprise a monolithic integrated circuit comprising an on-chip transceiver, digital baseband processing circuitry, and auxiliary interface circuitry. The on-chip transceiver may process a microwave signal from an antenna element to generate a first pair of quadrature baseband signals and convey the first pair of phase-quadrature baseband signals to the digital baseband processing circuitry. The auxiliary interface circuitry may receive one or more auxiliary signals from a source that is external to the monolithic integrated circuit and convey the one or more auxiliary signals to the digital baseband processing circuitry. The digital baseband processing circuitry may be operable to process signals to generate one or more second pairs of phase-quadrature digital baseband signals.

摘要： Methods and systems are provided for gain control during communications. A first electronic device may communicated data to a second electronic device; may monitor conditions and/or parameters affecting estimated reception performance at the second electronic device; and may communicated to the second electronic device, via a connection separate from and different than a connection used in communicating the data, information relating to the monitored conditions, to enable adjusting functions relating to reception of the data at the second electronic device. Based on the received information, at least one reception related function in the second electronic device may be controlled. The controlling may include determining, based on the received information, adjustments to the at least one reception related function or to a related parameter. The at least one reception related function may include applying gain to at least a portion of signals received by the second electronic device.

摘要： Methods and systems for a configurable low-noise amplifier with programmable band-selection filters may comprise a receiver with a low-noise amplifier (LNA) with first and second input terminals and differential output terminals; a low pass filter operably coupled to the LNA; a high pass filter operably coupled to the second input terminal of the LNA; and a signal source input coupled to the low pass filter and the high pass filter. The LNA may be operable to receive signals in a pass band of the high pass filter and a pass band of the low pass filter. The receiver may be operable to amplify input signals in the pass band of a first filter but not signals in the pass band of the second filter by operably coupling the second to ground.
