Abstract:
1. A method for decoding a succession of blocks of data encoded with a low-density parity-check (LDPC) code comprising: 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; defining a current indication representative of a threshold number of iterations for decoding a current block, the current indication initialized to a reference number of iterations increased by an additional number of iterations dependent on an additional memory size of the input memory for supplementary storage greater than two blocks; 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.
