Abstract:
Systems and methods are provided for decoding data. A decoder retrieves data related to a symbol and identifies a plurality of candidate values for the symbol. The decoder determines a distance between each of the plurality of candidate values and a reference value associated with the symbol to obtain a plurality of distances, and the decoder determines whether to update a value of the symbol based at least in part on the plurality of distances.
