APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA IN A COMMUNICATION SYSTEM USING LOW DENSITY PARITY CHECK CODE
摘要:
A method for transmitting data in a communication system using a Low Density Parity Check (LDPC) matrix. The method includes generating an LDPC codeword by encoding information data bits, interleaving the LDPC codeword, mapping the interleaved LDPC codeword to a modulation signal, and generating a mapped signal by mapping the LDPC codeword bits separately to a bit corresponding to a real part and a bit corresponding to an imaginary part of said modulation signal, among bits constituting the modulation signal, generating a modulation signal by high-order-modulating the mapped signal and Radio Frequency (RF)-processing the modulation signal, and transmitting the RF-processed signal via a transmission antenna.
