LDPC CODE TRANSMISSION METHOD USING ROW-ORTHOGONAL STRUCTURE, AND DEVICE THEREFOR

Title:

LDPC CODE TRANSMISSION METHOD USING ROW-ORTHOGONAL STRUCTURE, AND DEVICE THEREFOR

Document Type and Number:

WIPO Patent Application WO/2018/143743

Kind Code:

A1

Abstract:

A method for encoding a quasi-cyclic low-density parity-check (LDPC) code according to an embodiment of the present invention may comprise the steps of: generating a multi-edge LDPC code matrix including a high rate code matrix and a single parity check code matrix; and encoding a signal by using the multi-edge LDPC code matrix, wherein the single parity check code matrix includes a first matrix having a non-row-orthogonal structure matrix and a second matrix having a pure row-orthogonal structure, which are concatenated.
