Abstract
Provided is a method for decoding a non-binary (NB) low density parity check (LDPC) code at a user equipment (UE) that implements at least one variable nodes that receive a received signal of a wireless channel and deliver an input message to a check node and the check node that checks the input message and outputs an output message. The method includes receiving at least one input messages, generating a temporary vector by using the at least one input messages, searching for an element having a dominant value by checking the temporary vector, generating a configuration set, which is a check target, by using the element having the dominant value, and generating the output message by performing comparison with respect to the generated configuration set.
