摘要： Systems and methods for expanding capacity in a network without the use of frequency gaps between a legacy channel and/or newly added channels are provided. Systems and methods for maintaining legacy node operability in the expanded capacity network are also provided by determining the increased power experienced by a legacy node as a result of the newly added channels, and dynamically adapting the modulation utilized on the legacy channel commensurate with the increased power.

摘要： Systems and methods for removing interference from a received signal. A model of a leakage path from a transmit section to a receive section is used to assist in designing a set of iterative filters to remove interference. Modeling the leakage path allows generation of the first approximation of the transfer function of the leakage path traversed by the signals coupled from the transmit section to the receive section. The first approximation narrows down the universe of possible distortions that might occur due to the transfer function of the leakage path. Narrowing down the universe of possible solutions makes the complexity of the interference control section more manageable. An iterative LMS function is used to further refine the coefficients of the adaptive filters.

摘要： A method and apparatus in which a Tap-Weight Computer (TWC) calculates a Tap-Weight Vector (TWV). The TWV is coupled to a register in each of a plurality of adaptive filter modules. Each such adaptive filter module includes several adaptive filters that each include a tapped delay line. The input to the tapped delay line of each such adaptive filter is one of a plurality of potential interfering signals. The TWV controls the weighting of the outputs from the taps off the delay line. The weighted outputs from each tapped delay line are then subtracted from a received signal which potentially includes interference from the potential interfering signals. The TWC is multiplexed to each of the plurality of adaptive filters so that each adaptive filter is loaded with a TWV calculated by the TWC to reduce the amount of interference contributed by a particular potential interfering signal coupled to an input to that particular adaptive filter. In one embodiment, a plurality of such adaptive filter modules share the same TWC.

摘要： The use of traffic flag symbols allows a large number of CPEs to transmit traffic notifications to a network controller. In some such embodiments, hundreds of CPEs simultaneously transmit traffic flags on different subcarriers of a channel. For example, in a MoCA2 based access network, up to 480 CPEs can transmit flags in only 5 μs in the 100 MHz-wide channel.

摘要： A system for IQ balance estimation is disclosed and may include requesting an in-phase and quadrature (IQ) probe comprising tones, receiving the tones with a frequency separation between images of the tones, the frequency separation being a result of a frequency shift at a requestor of the IQ probe, and calculating an estimate of IQ imbalance for each received tone. The system may also include requesting an IQ probe, receiving the tones with a frequency separation, and calculating an estimate of IQ imbalance for each received tone by determining an image to tone ratio based on the received tones. The requesting of the IQ probe, the receiving of the tones, and the calculating of the image to tone ratio may be repeated the results of the calculations of the image to tone ratio may be averaged. Gain, phase, and delay parameters may be calculated to compensate for the IQ imbalance.
