摘要： The invention relates to a method for controlling a check node of a NB-LDPC decoder. The check node receives d c input lists U i and delivers and delivers d c output lists V i , with iˆˆE[1...d c ]. Each input list and output list comprises n m elements and each element of the input or output lists comprises a reliability value associated to a symbol of a Galois Field GF(q) with q>n m . 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 d c elements of input lists U i . The method comprises a step of syndrome calculation, a step of decorrelation and a step for generating the output list.
