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 signalinginformationare disclosed. A parity interleaving apparatus according to an embodiment ofthe presentinvention includes a processor configured to generate a parity bit string forparitypuncturing by segmenting parity bits of an LDPC codeword whose length is 16200andwhose code rate is 3/15, into a plurality of groups, and group-wiseinterleaving the groupsusing an order of group-wise interleaving; and memory configured to providethe parity bitstring for parity puncturing to a parity puncturing unit.
