Abstract
A receiver relates generally to channel adaptation. In this receiver, a first signal processing block is coupled to a communications channel. The first signal processing block includes: an AGC block and a CTLE block for receiving a modulated signal for providing an analog signal; an ADC for converting the analog signal to digital samples; and an FFE block for equalizing the digital samples to provide equalized samples. A second signal processing block includes: a DFE block for receiving the equalized sampled for providing re-equalized samples; and a slicer coupled to the DFE block for slicing the re-equalized samples. A receiver adaptation block is coupled to the first signal processing block and the second signal processing block. The receiver adaptation block is configured for providing an AGC adaptation, a CTLE adaptation, and a slicer adaptation to the communications channel.
