    Abstract: A network device may receive a signal from a headend, wherein a bandwidth of the received signal spans from a low frequency to a high frequency and encompasses a plurality of sub-bands. The network device may determine, based on communication with the headend, whether one of more of the sub-bands residing above a threshold frequency are available for carrying downstream data from the headend to the circuitry. The network device may digitize the signal using an ADC operating at a sampling frequency. The sampling frequency may be configured based on a result of the determining. When the sub-band(s) are available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively high frequency. When the sub-band(s) are not available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively low frequency.

    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: Methods and systems are provided for loop-through for multi-chip communication systems. Receiver circuitry, that is operable to receive one or more input feeds, may comprise a plurality of chips, each of which may be configurable to generate a corresponding output comprising one or more feed elements (e.g., channels) extracted from the input feed(s). However, only a first chip may be operable to handle reception and/or initial processing of the one or more input feeds, with each one of the remaining chips processing a loop-through feed generated by the first chip, in order to generate the corresponding output of that chip. The first chip generates the loop-through feed based on the one or more input feeds, such as after the initial processing thereof in the first chip. Generating the loop-through feed may comprise applying channelization (e.g., separately for each remaining chip), switching based processing, and/or interfacing based processing.

    Abstract: Methods and systems are provided for using frequency spreading during communications, in particular communications in which multiple carriers (or subcarriers) are used. The frequency spreading may comprise generating a plurality of spreading data vectors based on transmit data, such as by application of a spreading matrix to portions of the transmit data. Each spreading data vector may comprise a plurality of elements, for assignment to the multiple subcarriers. The receive-side device may then apply frequency de-spreading, to obtain the original transmit data. The frequency de-spreading may comprise use of the same spreading matrix on data extracted from received signals, which (the data) may correspond to the plurality of spreading data vectors.

    Abstract: A cable modem comprises transmitter circuitry, receiver circuitry, and memory. Upon power up of the cable modem in the field, the transmitter circuitry transmits one or more first signals into a network. The receiver circuitry measure echoes of the transmitted one or more first signals. The receiver circuitry generates an installation figure of merit based on the measured echoes and factory-calibration echo measurements stored in the memory. The communication device begins DOCSIS® network registration if the installation quality measurement meets a determined requirement and generates a notification to troubleshoot the installation of the communication device if the installation quality measurement does not meet a determined requirement.
