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.

Apparatus and method for determining log likelihood values of nodes in communication system supporting low density parity check code

An apparatus and a method for transmitting data using a fountain code are provided. The method for transmitting data includes determining a degree distribution of a fountain code based on erasure rate information regarding at least one receiving end, performing fountain encoding according to the degree distribution, and transmitting symbols generated by the fountain encoding.
