APPARATUS AND METHOD FOR INTERLEAVING/DE-INTERLEAVING SIGNAL IN A COMMUNICATION SYSTEM

摘要

An apparatus and a method for interleaving/deinterleaving a signal in a communication system are provided to prevent performance deterioration in an HOM method by transceiving signals through LDPC codes. An apparatus for interleaving/deinterleaving a signal in a communication system includes the steps of: receiving LDPC(Low Density Parity Check) codes; and interleaving the LDPC codes in correspondence to an interleaving method set by considering a modulation method used for a signal transmitting apparatus. The interleaving method is generated by considering at least one of a stopping set of a parity check matrix of the LDPC codes or a modulation order corresponding to the modulation method.
