Title:
METHOD AND APPARATUS FOR FAST DECODING OF LINEAR CODE ON BASIS OF SOFT DECISION
Document Type and Number:
WIPO Patent Application WO/2020/179966
Kind Code:
A1
Abstract:
Disclosed are a method and an apparatus for fast decoding of a linear code on the basis of soft decision. The method for fast decoding of a linear code on the basis of soft decision comprises the steps of: arranging received signals in order of magnitude so as to obtain alignment signals; performing hard decision on the alignment signals so as to obtain hard decision signals; obtaining upper signals corresponding to the most reliable bases (MRB) from the hard decision signals; obtaining a permuted and corrected codeword candidate by using the upper signals and an error vector according to the current order; calculating a cost for the current order by 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 pre-defined high-speed condition.
