Patent ID: 8037388

Claim:
A method for successively and individually decoding a plurality of blocks encoded with a Low Density Parity Check (LDPC) code, each block comprising a given number (N) of cues, the method comprising: using a decoder for initializing N channel cues, respectively, with the N cues of the block and metrics cues distributed within a metrics matrix including N columns and subdivided into a plurality of layers, each layer comprising a plurality of rows; and using the decoder for decoding each block iteratively by at least updating, layer-by-layer, the metrics cues distributed over the N columns of the plurality of layers, and updating the N channel cues respectively associated with the N columns of each layer; the metrics cues being situated in different rows for each layer; the updating of the N channel cues respectively associated with the N columns involving, at each iteration, a single updated metric cue selected from the metrics cues of a current column for a current iteration, a respective row of the selected single updated metric cue changing at each iteration.
