摘要: The present invention discloses a set-cyclic comparison method for an LDPC (Low-Density Parity-Check) decoder, which applies to a CNU (Check Node Unit) or a VNU (Variable Node Unit). In the systematized method of the present invention, all the input elements are initialized to obtain a matrix. Based on the symmetry of the matrix and the similarity between the rows of the matrix are sequentially formed different sets respectively corresponding to the horizontally-continuous elements having the maximum iteration number in the horizontal and vertical directions, the symmetric non-continuous non-boundary elements, and the boundary elements plus the end-around neighboring elements in the same row. The present invention applies to any input number. Via the large intersection between the compared sets, the present invention can effectively reduce the number of comparison calculations and greatly promote the performance of an LDPC decoder.
