Abstract
A permutation network designing method and a permutation circuit using the same are provided. The method includes: identifying a predetermined check matrix of the QC-LDPC decoder, wherein the check matrix comprises M×N sub-matrices, wherein each of the sub-matrices is a Z×Z matrix, wherein Z is a default dimension value of each of the sub-matrices; constructing a permutation network of a permutation circuit according to the default dimension value and a saving parameter, wherein the permutation network comprises a plurality of permutation layers arranged sequentially, and each of the permutation layers has the same amount of nodes, wherein the amount of the permutation layers and the amount of the nodes of each of the permutation layers are set according to the default dimension value and a saving parameter; and disposing a plurality of selectors on the nodes of the permutation network of the permutation circuit.
