Abstract

In a method for channel adaptation, an analog input signal is received with a bimodal receiver via a communications channel. The analog input signal is converted to a digital input signal with an analog-to-digital converter of a digital receiver of the bimodal receiver. Channel coefficients are detected for the digital input signal associated with the communications channel. The channel coefficients indicate a number of post-cursor taps of the bimodal receiver to be used to provide an equalized digital output signal from the digital input signal. It is determined whether the number of post-cursor taps or a value associated therewith is equal to or less than a threshold number. A switch from the receiving of the analog input signal by the digital receiver to an analog receiver of the bimodal receiver is made to provide the equalized digital output signal for the analog input signal.

First claim

What is claimed is:

1. A method for channel adaptation, comprising:
receiving an analog input signal with a bimodal receiver via a communications channel;
converting the analog input signal to a digital input signal with an analog-to-digital converter of a digital receiver of the bimodal receiver;
detecting channel coefficients for the digital input signal associated with the communications channel;
wherein the channel coefficients indicate a number of post-cursor taps of th…
