Abstract: Methods and systems for providing a home cable network may comprise, for example, in a premises-based wired network (network), receiving by a root node network controller (NC), signals that conform to first protocols, where the signals may be received from sources external to the premises. The received signals may be bridged to conform to a second communications protocol and communicated to one or more networked devices comprising a television set top box downstream from the root node device where, for example, only signals conforming to the second communications protocol may be communicated. The first protocol signals may comprise data over cable service interface specification (DOCSIS), cable television, satellite television, fiber-to-the-home, and/or digital subscriber (DSL) signals. The second communications protocol may, for example, comprise a multimedia over cable alliance (MoCA) standard. The bridged signals may be communicated to networked devices at a frequency that is independent of the first communications protocols.

Abstract: Systems and methods are provided for dynamic calibration of pre-distortion modification in transmitters. The pre-distortion modification may be applied during processing of an input signal for transmission, and feedback data, relating to the transmitter and/or processing performed after application of the pre-distortion modification in the transmitter, may be obtained. Adjustments to the pre-distortion modification may be determined based on the feedback data, and the adjustments to the pre-distortion modification may be applied in loop-back manner, thus enabling adjustment of pre-distortion modification dynamically based on real-time and current data. The pre-distortion modification may comprise modifying one or more signal characteristics, such as phase, frequency, and/or amplitude. Determining and/or applying the adjustments to the pre-distortion modification may be done periodically, based on one or more particular events, or conditionally.

Abstract: 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.

Abstract: Methods and systems for I/Q mismatch calibration and compensation for wideband communication receivers may comprise receiving a plurality of radio frequency (RF) channels, downconverting the received plurality of received RF channels to baseband frequencies, determining and removing average in-phase (I) and quadrature (Q) gain and phase mismatch of the downconverted channels, determining a phase and amplitude tilt of the downconverted channels with removed average I and Q gain and phase mismatch, and compensating for said phase and amplitude tilt I and Q gain and phase mismatch of the downconverted channels. The determined phase tilt may be compensated utilizing a phase tilt correction filter, which may comprise one or more all-pass filters. The average I and Q gain and phase mismatch may be determined utilizing a blind source separation (BSS) estimation algorithm.

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.

Abstract: Methods and systems for time interleaved analog-to-digital converter timing mismatch calibration and compensation may include receiving an analog signal on a chip, converting the analog signal to a digital signal utilizing a time interleaved analog-to-digital-converter (ADC), and reducing a blocker signal that is generated by timing offsets in the time interleaved ADC by estimating complex coupling coefficients between a desired digital output signal and the blocker signal utilizing a decorrelation algorithm on frequencies within a desired frequency bandwidth. The decorrelation algorithm may comprise a symmetric adaptive decorrelation algorithm. The received analog signal may be generated by a calibration tone generator on the chip. An aliased signal may be summed with an output signal from a multiplier. The complex coupling coefficients may be determined utilizing the decorrelation algorithm on the summed signals. A multiplier may be configured to cancel the blocker signal utilizing the determined complex coupling coefficients.
