摘要
Disclosed are a method and an apparatus for fast decoding a linear code based on soft decision. The method may comprise sorting received signals in a magnitude order to obtain sorted signals; obtaining hard decision signals by performing hard decision on the sorted signals; obtaining upper signals corresponding to MRBs from the hard decision signals; obtaining a permuted and corrected codeword candidate using the upper signals and an error vector according to a current order; calculating a cost for the current order using a cost function; determining the permuted and corrected codeword candidate as a permuted and corrected codeword according to a result of comparing the calculated cost with a minimum cost; and determining a predefined speeding condition.
