Provided are a data receiving device and a corresponding method for receiving the data. The data receiving device comprises a path control logic configured to store L symbol paths, where L is a natural number equal to or greater than 2, L feedback filters configured to calculate L inter-symbol interferences (ISI) for the L symbol paths, respectively, L operators configured to remove the L inter-symbol interferences from an output of a feed-forward equalizer, and a path metric calculator configured to receive outputs of the L operators and calculate a path metric for each of the L symbol paths, wherein the path control logic is configured to select L values among the calculated path metrics for the L symbol paths to update the L symbol paths.
