PARITY INTERLEAVING APPARATUS FOR ENCODING FIXED-LENGTH SIGNALING INFORMATION, AND PARITY INTERLEAVING METHOD USING SAME

摘要

A parity interleaving apparatus and method for fixed-length signaling information are disclosed. The parity interleaving apparatus according to one embodiment of the present invention comprises: a processor which divides, into a plurality of groups, parity bits of an LDPC code word having a length of 16200 and a code rate of 3/15, and generates a parity bit string for parity puncturing by group-wise interleaving the groups using a group-wise interleaving order; and a memory for providing the parity bit string for parity puncturing to a parity puncturing unit.
