Abstract
There is provided an encoder that provides a termination sequence with a simple structure for LDPC-CC encoding and reduces an amount of the termination sequence transmitted to a transmission line. The LDPC-CC encoder connects a first encoder to a second encoder to perform encoding and thereby carry out LDPC-CC encoding, the first encoder performing encoding based on an partial parity check matrix for information bits obtained by extracting a sequence corresponding to the information bits in a parity check matrix and the second encoder performing encoding based on a partial parity check matrix for parity bits obtained by extracting a sequence corresponding to the parity bits in the parity check matrix. A termination sequence generator generates a termination sequence including the same number of bits as the memory length of the first encoder and provides the generated termination sequence as an input sequence.
