摘要： Herein described are at least a method and a system for implementing a high speed Tomlinson-Harashima Precoder. The method comprises using an L-tap transpose configuration of a Tomlinson-Harashima Precoder and processing a first discrete time sampled sequence using said L coefficients and L state variables by clocking the L-tap Tomlinson-Harashima Precoder using a clock signal wherein the clock signal has a clock rate equal to one half the symbol rate of the discrete time sampled sequence. In a representative embodiment, an L-tap Tomlinson-Harashima Precoder comprises a single integrated circuit chip, wherein the integrated circuit chip comprises at least one circuitry for processing a discrete time sampled sequence using L coefficients and L state variables by way of clocking the discrete time sampled sequence using a clock signal having a clock rate that is one half the symbol rate of the discrete time sampled sequence.

摘要： Aspects of a method and system for unconstrained frequency domain adaptive filtering include one or more circuits that are operable to select one or more time domain coefficients in a current filter partition. A value may be computed for each of the selected one or more time domain coefficients based on a corresponding plurality of frequency domain coefficients. The corresponding plurality of frequency domain coefficients may be adjusted based on the computed values. A subsequent plurality of frequency domain coefficients in a subsequent filter partition may be adjusted based on the computed values. Input signals may be processed in the current filter partition based on the adjusted corresponding plurality of frequency domain coefficients. A time-adjusted version of the input signals may be processed in a subsequent filter partition based on the adjusted subsequent plurality of frequency domain coefficients.

摘要： Aspects of a method and system for interference cancellation substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims. In this regard, a receiver may be operable to receive a differential signal via a differential channel, and to sense a common mode signal on the differential channel. A frequency range in which interference is present in the common mode signal may be determined. The differential signal and the common mode signal may be filtered to attenuate frequencies outside the determined frequency range. A phase and/or amplitude of the filtered common mode signal may be adjusted based on the filtered differential signal and the adjusted and filtered common mode signal may be subtracted from the received differential signal. The common mode signal may be sensed via a pair of resistors coupled to the differential channel.

摘要： Aspects of a method and system for adaptive tone cancellation for mitigating the effects of interference are provided. In this regard, an Ethernet PHY may receive one or more signals via a corresponding one or more physical channels and generate one or more estimate signals, each of which approximates interference present in a corresponding one of the received signals. The Ethernet PHY may subtract each one of the estimate signals from a corresponding one of the received signals. The subtracting may occur at the input of one or more slicers in the Ethernet PHY. The received signals may be processed via one or more equalizers in the Ethernet PHY. A decision output of a slicer in the Ethernet PHY may be subtracted from one of the said one or more received signals, and a signal resulting from the subtraction may be utilized to generate the one or more estimate signals.
