Abstract
A method of selecting filter patterns is provided. The method may include measuring an average sign value of aggregate inter-symbol interference (ISI) for a data sequence using multiple filter pattern combinations of multiple filter patterns; estimating a first analog level of aggregate ISI for a first filter pattern based on a first average sign value, and a second analog level of aggregate ISI for a second filter pattern based on a second average sign value; estimating an analog level of individual ISI of the first filter pattern pair based on the first analog level and the second analog level; estimating, for each possible filter pattern combination, an analog level of aggregate ISI for the first filter pattern pair; and selecting a filter pattern combination for the first filter pattern pair that reduces the analog level of aggregate ISI.
