Abstract: Characterization and assessment of communication channel average group delay variation. A signal having repeated signal components therein is received by a communication device, and that signal undergoes appropriate processing to determine respective amplitude and phase of a number of frequency bins. The phase difference from bin to bin (including respecting unwrapping, and proper normalization) is used to determine the group delay of a communication channel, or portion thereof, as a function of frequency. Multiple respective group delay measurements may be averaged to generate a wideband group delay of the communication channel as a function of frequency. Overlap between different respective band-edge portions of the communication channel may assist in generating a seamless continuous wideband spectrum estimation for use in determining the wideband group delay of the communication channel.

Abstract: Narrowband ingress estimation and characterization using equalizer taps. A equalizer including a feed forward equalizer (FFE) and a decision feedback equalizer (DFE) is implemented to process an input signal thereby generating an output signal. Analysis of the frequency response of the equalizer including the FFE and the DFE of the equalizer allows for the determination of whether or not narrowband ingress exists within the signal received by the equalizer. For example, analysis of the signal output from the equalizer provides for determination of the overall frequency response of the equalizer. In addition, analysis of the respective equalizer coefficients within one or both of the FFE and the DFE of the equalizer may be used to determine the overall frequency response of the equalizer. Narrowband ingress may be identified when the combination of the FFE (having a notch therein) and the DFE provides for an overall flat frequency response.

Abstract: A method for increasing upstream bandwidth per cable modem user in a cable communications system that includes a cable modem termination system (CMTS) and a plurality of cable modems is provided. The method permits a cable modem to transmit data to the CMTS on multiple upstream channels simultaneously using a technique called “channel bonding.” Bandwidth allocation is achieved by transmitting from a CMTS to a cable modem a unique bandwidth allocation message for each upstream channel in a bonded group of upstream channels, wherein the combination of unique bandwidth allocation messages collectively allocates requested bandwidth across the bonded group.

Abstract: In a DOCSIS-based communications system, different upstream channel descriptors (UCDs) all identify a single logical upsteam channel identifier (UCID) regardless of the type of cable modem (CM) to which the UCDs are sent. Different CMs having different capabilities (e.g., CMs configured according to the different DOCSIS standards 1.x, 2.0, and 3.0) receive their respective UCDs from an upstream headend. All the UCDs, however, refer to the same logical upstream channel. The different CMs therefore share this single logical upstream channel.
