Soft value flipping decoding algorithm for LDPC codes based on adjoint vectors sum
By analyzing the soft value distribution while belief propagation defeated, a soft value flipping decoding algo-rithm based on adjoint vectors sum was presented.With translating the error times of check equation which obtained by adjoint vectors sum into error bits distribution parameter and flippin...

| description | By analyzing the soft value distribution while belief propagation defeated, a soft value flipping decoding algo-rithm based on adjoint vectors sum was presented.With translating the error times of check equation which obtained by adjoint vectors sum into error bits distribution parameter and flipping some bit nodes soft value only once at certain itera-tion by a selection regulation, the frame error rate of the proposed algorithm for LDPC codes which have much more correlative rows can be reduced to a larger extent without complexity increase nearly（only O（N））. |
