Abstract: Systems and methods are provided for utilizing ideal taps in coaxial networks. An ideal tap may have a plurality of ports that include at least an input port configured for receiving downstream (DS) signals from and transmitting upstream (US) signals to nodes upstream from the tap within the coaxial network; an output port configured for transmitting downstream (DS) signals to and receiving upstream (US) signals from nodes downstream from the tap within the coaxial network; and one or more drop ports for receiving signal from and transmitting signals to customer premise equipment (CPE) in the coaxial network. The ideal tap may further include processing circuits for handling signals received and transmitted via the tap, with the one or more processing circuits being configured to meet particular predefined tap performance criteria, where the particular predefined tap performance criteria comprise one or more of high return loss, high port-to-port isolation, and high port-to-port gain.

Abstract: Systems and methods are provided for distortion redirection in phased arrays. In an electronic device configured for transmission and reception of signals and having a two-dimensional phased array, effects of distortion, corresponding to at least one processing function applied during communication of signals, on the communication of signals may be assessed, and based on the effects of distortion, one or more adjustments for mitigating the effects of distortion may be configured and applied during processing of signals. Assessing the effects of distortion may include determining one or more characteristics associated with the communication of the signals, where the one or more characteristics relate and/or are subject to the effects of the distortion, and assessing the effects of distortion based on the one or more characteristics.

Abstract: Methods and systems are provided for adaptive management of local networks, such as in-premises networks, which may have access to and/or may be connected to external networks, such cable or satellite networks. A network management device that manages a local network may receive from a client device in the local network, a communication request relating to communication within the local network, may process the communication request, and may configure the communication of the client device based on processing of the communication request. The processing of the communication request may include assessing effects of communication of the client device, at the network management device, on other connections and/or communications, with the other connections and/or communications including external connections and/or communications with one or more devices and/or networks external to the local network. Processing of the communication request may include assessing likelihood of interference at the network management device.

Abstract: A cable modem comprises transceiver circuitry and echo cancellation training circuitry. The transceiver circuitry may be operable to transmit and receive signals on a full-duplex Data Over Cable System Interface Specification (DOCSIS®) network. The echo cancellation training circuitry may be operable to: determine an echo cancellation training group to which the electronic communication device belongs; determine one or more training periods during which the echo cancellation training group is permitted to transmit training signals; and transmit an echo cancellation training signal during the determined training one or more periods and use the transmitted training signal to train echo cancellation circuitry of the cable modem.

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: An electronic communication device comprises echo cancellation circuitry and signal modification circuitry. The echo cancellation circuitry may be operable to generate a first signal that approximates interference present in a second signal. The signal modification circuitry may be operable to generate a first cancellation signal in a frequency band that is not used on a communication medium over which the electronic communication device is configured to communicate. The signal modification circuitry may be operable to combine the first cancellation signal with the first signal, wherein the combining of the signals results in a modified first signal that has a lower crest factor and/or peak-to-average power ratio than the first signal. The signal modification circuitry may be operable to combine the modified first signal with the second signal to reduce interference present in the second signal.

Abstract: A remote PHY comprises circuitry operable to communicate with a converged cable access platform and a plurality of cable modems in accordance with Data Over Cable Service Interface Specification (DOCSIS®). The remote PHY comprises buffer circuitry operable to buffer signals to be transmitted to one or more of the plurality of cable modems. The remote PHY may comprise subcarrier insertion circuitry operable to manipulate the contents of the buffer circuitry such that the remote PHY is scheduled to transmit, during a determined time interval, subcarriers having determined characteristics. The subcarriers having determined characteristics may be zero-bit-loaded subcarriers.

Abstract: Systems and methods are provided for peak to average power ratio (PAPR) reduction in multichannel transmissions. A plurality of frequency-domain symbols may be generated and assigned to a plurality of subcarriers associated with a multichannel transmission. The subcarriers may be assigned to a plurality of channels used for the multichannel transmission, with a number of the channels being different than a number of the subcarriers. A plurality of time-domain signals corresponding to the plurality of channels may be generated, and an adjustment may be applied to at least one time-domain signal, to generate a corresponding adjusted time-domain signal. The adjustment may be configured based on one or more characteristic associated with at least two of the frequency-domain symbols. Handling related information may be communicated form the transmit-side to the receive-side, such as using spare carriers, to enable handling an output corresponding to the plurality of time-domain signals.
