Abstract
The invention relates to an apparatus and a method for generating a Low-Density Parity-Check (LDPC) code. The apparatus includes: a LDPC encoder, a look-ahead circuitry and an exclusive-OR (XOR) calculation circuitry. The LDPC encoder is arranged operably to encode a front part of a user data using a 2-stage encoding algorithm with a parity check matrix to generate a first calculation result. The look-ahead circuitry is arranged operably to perform a dot product operation on a rear part of the user data and one of a plurality of feature rows corresponding to the parity check matrix to generate a second calculation result in each iteration. The XOR calculation circuitry is arranged operably to perform an XOR operation on the first calculation result and the second calculation result to generate a front part of the LDPC code.
