Title:

APPARATUS AND METHOD FOR ENCODING AND DECODING CHANNEL IN COMMUNICATION OR BROADCASTING SYSTEM

Document Type and Number:

WIPO Patent Application WO/2017/111559

Kind Code:

A1

Abstract:

The present invention related to a 5G or pre-5G communication system to be provided to support a higher data transmission rate since 4G communication systems like LTE. The present invention relates to a method and an apparatus for encoding a channel in a communication or broadcasting system supporting parity-check matrices having various sizes are provided. The method for encoding a channel includes determining a block size of the parity-check matrix; reading a sequence for generating the parity-check matrix, and transforming the sequence by applying a previously defined operation to the sequence based on the determined block size.
