    摘要: Processing signals in a digital communication may include equalizing a signal in a timing-recovery system using a frequency domain equalizer. The frequency domain equalizer may be a frequency domain adaptive filter that adapts using a least-mean-square algorithm where at least one tap-weight that corresponds to a pre-cursor may be constrained to zero. The processing may include recovering timing information using a Mueller/Muller timing recovery algorithm that may be aided by using a pre-filter before the equalizer.

    摘要: A system and method for dynamic power control for energy efficient physical layer communication devices. Energy-efficiency features are continually being developed to conserve energy in links between such energy-efficient devices. These energy-efficient devices interoperate with many legacy devices that have already been deployed. In these links, energy savings can be produced by having a local receiver enter an energy saving state based upon the receipt of standard IDLE signals.

    摘要: One or both link partners coupled via an Ethernet link may comprise a PHY device operable to initiate a wake-up interval. The PHY device may monitor parameters that may indicate Ethernet link status. Exemplary parameters may comprise a timer, communication performance metrics and/or configuration parameters. From a low power mode, the PHY device may generate a wake state idle symbol based on the monitoring and may communicate it to a local and/or a remote MAC. The local and/or remote MAC may establish a wake-up interval. The wake-up interval may comprise synchronization, circuit adaption and updating of communication parameters, which may enable control of noise cancellation functions and/or equalization functions. One or both of the link partners may transition to a low power mode after the wake-up interval and/or to an active state after the wake-up interval.
