This abstract first appeared for US patent application 18490051 titled 'BIT-FLIPPING DECODER AND DECODING METHOD BASED ON SUPER NODE
Original Abstract Submitted
A bit-flipping (BF) decoder and a decoding method based on a super node, which groups two or more component nodes corresponding to two or more bits in a codeword to generate a super node; and performs a decoding iteration on the super node. The decoding iteration includes: calculating a flipping energy for the super node based on a flipping energy for each of the component nodes and internal checks between the component nodes; and flipping at least one of the two or more bits in the super node upon a determination that the flipping energy for the super node exceeds a bit-flipping threshold.
