Abstract:
A method is for decoding a succession of blocks of data encoded with an LDPC code. The method includes storing the blocks temporarily and successively in an input memory before decoding the blocks successively in an iterative manner, the input memory having a memory size for storage of at least two blocks, and defining a current indication representative of a threshold number of iterations for decoding a current block. The method includes decoding the current block until a decoding criterion is satisfied or so long as a number of iterations performed for decoding the current block has not reached the current indication while at least one of a first subsequent block and a part of a second subsequent block are stored in the input memory, and updating the current indication for decoding the first subsequent block as a function of the number of iterations performed for decoding the current block.
