Abstract
Provided are a decoding system including a receiving device and a transmitting device. The receiving device comprises a demapper configured to convert received data into a log likelihood ratio (LLR) signal and output the LLR signal, a deparser configured to rearrange the LLR signal by deparsing the LLR signal into orthogonal frequency division multiplex (OFDM) symbols, a codeword loader configured to output the rearranged LLR signal in units of codewords, a decoder controller configured to control a maximum iteration number and the number of decoders to be enabled according to a state of the received data and a low-density parity check (LDPC) decoder configured to repeatedly decode the LLR signal in units of codewords, according to the controlled number of decoders, as many times as the controlled maximum iteration number, wherein the received data comprises real data and a packet extension corresponding to a pre-FEC (forward error correction) padding factor.
