Abstract
An apparatus and a method for receiving a signal in a communication system using a Low Density Parity Check (LDPC) code. The apparatus and the method includes decoding a received signal according to a hybrid decoding scheme, wherein the hybrid decoding scheme is generated by combining two of a first decoding scheme, a second decoding scheme, and a third decoding scheme.
