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.

Description

technical field [0001] The present invention relates to a wireless local area network (LAN) system, and more particularly to a method of transmitting an LDPC code using a row-orthogonal structure in a system supporting a Low Density Parity Check (LDPC) code and an apparatus supporting the same. Background technique [0002] Wireless access systems have been widely deployed to provide various communication services, such as voice communication services and data communication services. In general, a wireless access system is a multiple-access system capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmission power, etc.). For example, multiple-access systems may include Code Division Multiple Access (CDMA) systems, Frequency Division Multiple Access (FDMA) systems, Time Division Multiple Access (TDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple ...
