APPARATUS AND METHOD FOR RECEIVING DATA IN A COMMUNICATION SYSTEM

摘要

The present invention relates to an apparatus and a method for receiving data using a low-density parity check (LDPC) decoding scheme in a digital broadcasting system. The method comprises calculating a parity check matrix of a trellis coded modulation symbol from data that is received via an antenna; transforming the calculated parity check matrix into a low-density parity check matrix; decoding the data having been received via the antenna, based on the transformed low-density parity check matrix; and recovering the data having been received via the antenna.
