APPARATUS OF PARITY INTERLEAVING FOR ENCODING VARIABLE-LENGTH SIGNALING INFORMATION AND METHOD USING THE SAME

摘要

Disclosed are a parity interleaving apparatus for variable length signaling information and a parity interleaving method using the same. According to an embodiment of the present invention, the parity interleaving apparatus comprises a memory and a processor. The processor divides parity bits in an LDPC encoding language having the length of 16200 and an encoding ratio of 3/15 into a plurality of groups, and generates a parity bit string for puncturing parity by group-wise interleaving the groups by using a group-wise interleaving order. The memory supplies the parity bit string for puncturing parity to a parity puncturing unit.
