    • A method of controlling the operation of an equalizer (210, 216), wherein the equalizer is adapted to receive a transmitted signal (76, 78) comprising at least one predetermined sequence of symbols, includes the step of developing a set of samples from a received signal. At least one plurality of samples is identified, wherein the at least one plurality of samples corresponds to the at least one predetermined sequence of symbols. The equalizer is then operated in a selected one of three modes. A first mode is selected if the at least one plurality of samples is identified, wherein the first mode includes the step of developing a signal-to-noise ratio (SNR) (100). A second mode is selected if the at least one plurality of samples is identified and the SNR is greater than a first predetermined threshold. A third mode is selected if the at least one plurality of samples is identified and the SNR is greater than a second predetermined threshold.
    • 一种控制均衡器(210,216)的操作的方法,其中所述均衡器适于接收包括至少一个预定符号序列的发送信号(76,78),所述方法包括步骤 从接收信号开发一组样本。 识别至少一个多个样本,其中至少一个多个样本对应于至少一个预定符号序列。 然后均衡器以三种模式中的选定模式运行。 如果至少一个多个采样被识别,则选择第一模式,其中第一模式包括产生信噪比(SNR)(100)的步骤。 如果至少一个多个采样被识别并且SNR大于第一预定阈值,则选择第二模式。 如果至少一个多个采样被识别并且SNR大于第二预定阈值,则选择第三模式。
