Abstract
The disclosure relates to an LDPC decoding method which involves performing iterations until a stop criterion is satisfied. Each iteration involves computing variable messages (α), computing parity check messages (β), and computing a posteriori estimation variables. Computing a parity check message (β) for a parity check node (CN) involves determining the two smallest values (Mini1, Min2) among the absolute values of the variable messages associated with the parity check node (CN), comparing a difference between said values with a threshold, determining a correction value according to the result of the comparison, and computing the parity check message according to the correction value.
