    Abstract: A communication device is configured to encode information bits using one or more forward error correction (FEC) codes and/or error correction codes (ECCs) to generate different codewords (e.g., codeword groups having different lengths, based on different code rates, etc.). The device generates a combined codeword using different sized codewords (e.g., long, medium, and short) by filling fills long codewords completely if possible, then filling medium codewords completely if possible with the remaining message bits (if any), and filling short codewords completely if possible plus another additional short codeword with the remaining message bits (if any). If the total number of short (or medium and short) codeword parity bits is greater than or equal to the number of medium (or long) codeword parity bits, then the device increments the number of medium (or long) codewords by one and setting the number of short (or medium and short) codewords to zero.

    Abstract: A sparse equalizer system is disclosed. One or more multiple tapped delay lines (e.g., equalizers and/or pre-equalizers) are implemented to service one or more respective channels with which a communication device operates to support communications with at least one other communication device. Adaptive selection of which subsets of taps of the one or more multiple tapped delay lines is made to control those particular taps of which contribute to one or more subsequent slicer inputs. Those taps which are not currently operating to contribute to the slicer input may undergo processing, updating, etc. in parallel with or simultaneously with the processing of a signal to generate the outputs to be provided to the one or more subsequent slicers.

    Abstract: A communication device (e.g., a cable modem (CM)) includes a digital to analog converter (DAC) and a power amplifier (PA) that generate a signal to be transmitting via a communication interface to another communication device (e.g., cable modem termination system (CMTS)). The CM includes diagnostic analyzer that samples the signal based on a fullband sample capture corresponding to a full bandwidth and/or a subset (e.g., narrowband) sample capture to generate a fullband and/or subset signal capture (e.g., of an upstream (US) communication channel between the CM and the CMTS). The diagnostic analyzer can be configured to generate sample captures of the signal based on any desired parameter(s), condition(s), and/or trigger(s). The CM then transmits the signal to the CMTS and the fullband and/or subset signal capture to the CMTS and/or a proactive network maintenance (PNM) communication device to determine at least one characteristic associated with performance of the US communication channel.

    Abstract: A communication device (alternatively, device) includes a processor configured to support communications with other communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other communication device(s) and to generate and process signals for such communications. A device directs an analog to digital converter (ADC) to perform a sample capture of a communication channel and processes that sample capture to generate a detected power. The device performs an integrate-and-dump (I&D) operation on the detected power over at least one time period to generate an integrated power and then generates an integrated power histogram of the communication channel that includes the integrated power. This integrated power histogram characterizes noise generated by the device, noise entering the device, noise associated with the communication channel, etc.
