Abstract
A method for generating an LDPC (low-density parity check) code with a required error floor, comprising: using a parity generation circuit to generate an LDPC code; using a detection circuit to detect the LDPC code according to a plurality of trapping set cores in a database and to generate at least one piece of trapping-set-core information; using a verification circuit to perform an important sampling simulation according to the LDPC code and each trapping-set-core information separately to obtain an estimated error floor for each trapping-set-core information; using the verification circuit to separately compare each of the estimated error floors with an expected error floor; and when all of the estimated error floors are lower than or equal to the expected error floor, using the verification circuit to output the LDPC code.
