Abstract
In a communication system, a signal transmission apparatus includes an encoder for encoding an information vector into a low density parity check (LDPC) codeword with an LDPC coding scheme, and a puncturer for puncturing the LDPC codeword according to a coding rate using a puncturing scheme. A signal reception apparatus includes a ‘0’ inserter for inserting ‘0’ symbols in a received signal according to a coding rate used in a signal transmission apparatus, and a decoder for decoding the ‘0’ symbol-inserted signal with a decoding scheme corresponding to a low density parity check (LDPC) coding scheme used in the signal transmission apparatus, thereby detecting an information vector.
