Demodulator for a Multi-Pair Gigabit Transceiver

A transceiver comprising:

• an adaptive noise cancellation element operable to reduce a noise component of a received signal and output a noise-reduced signal;
• a gain stage operable to adjust the amplitude of the noise-reduced signal;
• and
• a decoder operable to decode the amplitude-adjusted, noise-reduced signal;
• wherein the adaptive noise cancellation element is adaptive based on a normalized adaptation error that is determined by dividing a decoder error of the decoder by a gain value of the gain stage.

A method of processing a received communication signal, comprising:

• reducing a noise component of the received signal using an adaptive noise cancellation element and outputting a noise-reduced signal;
• adjusting the amplitude of the noise-reduced signal using a gain value;
• decoding the amplitude-adjusted, noise-reduced signal using a decoder;
• and
• adapting the adaptive noise cancellation element based on a normalized adaptation error that is determined by dividing a decoder error of the decoder by the gain value.
