Some embodiments are directed to a method for controlling a check node of a NB-LDPC decoder. The check node receives dinput lists Uand delivers and delivers doutput lists V, with i&#x2208;[1 . . . d]. Each input list and output list includes nelements and each element of the input or output lists includes a reliability value associated to a symbol of a Galois Field GF(q) with q&#x3e;n. The input elements and output elements are sorted according to the reliability values in the lists. The method is a syndrome-based method. The syndromes are sums of delements of input lists U. The method includes a step of syndrome calculation, a step of decorrelation and a step for generating the output list.

Method for controlling a check node of a NB-LDPC decoder and corresponding check node

A method of decoding a received systematic code encoded block corresponding to an original block of information, wherein the received systematic code encoded block may include soft systematic values, may include detecting an error condition in the received systematic code encoded block. The method may also include decoding the received systematic code encoded block for retrieving the original block of information if the error condition in the received systematic code encoded block is detected and processing the soft systematic values to retrieve the original block of information instead of the decoding if the error condition in the received systematic code encoded block is not detected.
