摘要： A method and system to dynamically manager power in a communication system are provided herein. The method comprises the steps of monitoring a transmit data queue once every first pre-determined period of time and determining whether the transmit data queue is empty for a pre-determined number of times. The method further includes the step of generating a transition state signal to stop de-queuing of data from the transmit queue if the transmit data queue is empty for the pre-determined number of times and selectively operating portions of a Physical Layer (PHY) that are used for functions other than transmitting and receiving an idle signal in a low power mode.

摘要： Transceiver self-diagnostics for electromagnetic interference (EMI) degradation in balanced channels. Selective operation of transmitting a common mode signal from a communication link implemented for supporting differential signaling, and appropriate processing of any detected signal energy, such as that corresponding to differential signal energy, provides a measure of electromagnetic compatibility (EMC) corresponding to the communication link. Comparison of detected differential signal energy to one or more thresholds may provide indication of whether or not the communication link is balanced or unbalanced, a degree or margin with which the communication link is compliant in accordance with EMC in accordance with one or more protocols, standards, or recommended practices. Multiple successive measurements of detected differential signal energy may be used to determine a trend of performance, such as whether or not the communication link is trending toward imbalance, failure, or noncompliance.

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.

摘要翻译： 处理数字通信中的信号可以包括使用频域均衡器来均衡定时恢复系统中的信号。 频域均衡器可以是频域自适应滤波器，其使用最小均方算法进行调整，其中对应于前导的至少一个抽头可以被约束为零。 处理可以包括使用Mueller / Muller定时恢复算法来恢复定时信息，该算法可以通过在均衡器之前使用预滤波器来辅助。
