Abstract
A method for performing adaptive equalization includes: dynamically detecting current levels of a plurality of sets of pattern levels respectively corresponding to a plurality of data patterns, wherein each set of the sets of pattern levels includes a previous level, a current level, and a next level respectively corresponding to one of the plurality of data patterns; and dynamically calculating a plurality of data decision levels according to the current levels of the sets of pattern levels, for use of data decision, wherein each data decision level of at least one portion of the plurality of data decision levels is not equal to zero, and the data decision levels are dynamically adjusted in accordance with the current levels of the sets of pattern levels, in order to enhance a signal-to-noise ratio (SNR). An associated method for performing adaptive equalization is also provided. Associated apparatus are also provided.
