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： Communication devices coupled via a communication link may comprise physical layer devices that may be operable to determine presence of a received signal and to mitigate noise in the signal prior to processing and/or validating the signal. Analog and/or digital signal processing may be utilized to process the signal and/or mitigate noise in the signal. Noise mitigation may comprise near-end crosstalk cancelling and/or echo cancelling and/or may utilize local transmit signal information. Subsequent to noise mitigation, samples of the noise reduced signal may be accumulated and/or an average signal strength and/or average signal power level may be determined. The average signal strength and/or average signal power level may be compared to one or more thresholds which may be configurable and/or programmable.

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.

摘要： A system and method for loop timing update of energy efficient physical layer devices using subset communication techniques. During a quiet period during which a subset of communication channels are transitioned from an active mode to a low-power mode, circuitry in the active channel can be designed to track, on behalf of the inactive channels, the phase drift due to the frequency offset. This tracking of the frequency estimation error would reduce the time required to perform a timing update for the communication channels when transitioning back to the active mode.
