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 a long term evolution (LTE). A method of a receiving apparatus in a communication system supporting a low density parity check (LDPC) code is provided. The method includes deactivating variable nodes of which absolute values of log likelihood ratio (LLR) values are greater than or equal to a first threshold value; changing LLR values of variable nodes of which absolute values of LLR values are less than a second threshold value among variable nodes other than the deactivated variable nodes to a preset value, and detecting LLR values of check nodes based on LLR values of the variable nodes other than the deactivated variable nodes.

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). Disclosed is an apparatus for performing an iteration decoding scheme for a Low Density Parity Check (LDPC) code. The apparatus includes a receiver configured to receive an encoded signal based on a parity matrix set for a plurality of variable nodes including a first variable node with a first degree and a second variable node with a second degree. The apparatus further includes a processor configured to determine at least one variable node based on a first threshold determined according to the first degree and a second threshold determined according to the second degree among the plurality of variable nodes and to generate decoded data from the signal based on the at least one determined variable node.
