Abstract:
The method includes defining from all the check nodes at least one group of check nodes mutually connected through at least one second variable node defining an internal second variable node. The method includes performing for each group the joint updating of all the check nodes of the group via a Maximum-A-Posteriori (MAP) type process, and the updating of all the first variable nodes and all the second variable nodes connected to the group except the at least one internal second variable node. The method may include iteratively repeating the updates.
