Apparatus and method for mapping and demapping signals in a communication system using a low density parity check code |
摘要 |
An apparatus and method for mapping and demapping signals in a system using a Low Density Parity Check (LDPC) code are provided. In the method, LDPC codeword bits are written column-wise and read row-wise, substreams are generated by demultiplexing the read bits using a demultiplexing scheme, and bits included in each of the substreams are mapped to symbols on a signal constellation, wherein the demultiplexing scheme is determined corresponding to a modulation scheme used in the signal transmitter, a length of the LDPC codeword, and a number of the substreams. |
