Title:
APPARATUS AND METHOD FOR DECODING OF LOW-DENSITY PARITY CHECK CODES IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/226304
Kind Code:
A1
Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system, such as long-term evolution (LTE). The disclosure provides decoding of a low-density parity-check (LDPC) code in a wireless communication system, and a decoding method of the LDPC code may include receiving a codeword, performing decoding iterations on the codeword a predefined maximum number of times using a parity check matrix, performing partial decoding using a partial area of the parity check matrix, and determining decoding success or failure of the codeword based a result of the partial decoding.
