Abstract

A method for channel encoding in a communication or broadcasting system is provided. The method includes determining a block size Z, and performing encoding based on the block size and a parity checkmatrix corresponding to the block size, wherein the parity check matrix is determined based on a base matrix and a plurality of circulant permutation matrices, and wherein a part of a column index indicating a position of a non-zero element in each row of the base matrix includes an index according to mathematical expression 22 above.

Description

Technical field [0001] The present disclosure relates to an apparatus and method for channel encoding / decoding in a communication or broadcasting system. More specifically, the present disclosure relates to an apparatus and method for Low Density Parity Check (LDPC) encoding / decoding capable of supporting various input lengths and encoding rates. Background technique [0002] In order to meet the demand for wireless data services that have grown since the deployment of the fourth generation (4G) communication system, efforts have been made to develop an improved fifth generation (5G) communication system or pre-5G communication system . Therefore, the 5G or pre-5G communication system is also referred to as "super 4G network" or "Long Term Evolution (LTE) system". [0003] The 5G communication system is considered to be implemented in a higher frequency millimeter wave (mmWave) frequency band (for example, the 60 GHz frequency band) in order to achieve a higher data rate. In ord...
