IMPROVEMENTS TO A LAYERED DECODING APPROACH FOR LOW DENSITY PARITY CHECK (LDPC) CODES

摘要

A method of decoding in layers data received in a communication system, comprising receiving a codeword containing a plurality of elements (200) and translating the plurality of elements into probability values by dividing the rows of at least one column of a parity check matrix associated with the codeword into groups (204) and processing at least some of the groups separately (206).
