Title:
METHOD FOR SELECTING LDPC BASE CODE IN MULTI-LPDC CODE, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/128435
Kind Code:
A2
Abstract:
A method for encoding a quasi-cyclic low-density parity-check (LDPC) code which supports a multi-base code according to an embodiment of the present invention includes: a step for selecting a base code for generating a parity-check matrix from among a first base code and a second base code; a step for selecting a lifting value for generating the parity-check matrix from among a plurality of lifting values; and a step for generating the parity-check matrix using the selected base code and lifting value, wherein the base code can be determined on the basis of the code block size and a code rate, and the lifting value can be determined on the basis of a parameter of the base code and the code block size.
