Abstract
The disclosure relates to an LDPC decoding method which involves performing iterations until a stop criterion is satisfied. Each iteration involves calculating variable messages (α), calculating parity check messages (β), and calculating a posteriori estimation variables. The parity check messages (β) and the posteriori estimation variables (γn) being saturated at a predetermined maximum value. At the end of an iteration, when the number of saturations reaches a specified threshold, the method involves at least a first scaling of the parity check messages (β) and the a posteriori estimation variables (γ). Scaling corresponds to assigning, to a value, an integer which has the same sign and whose absolute value is the nearest integer greater than the absolute value of the value divided by two.
