ENCODER AND ENCODING METHOD |
摘要 |
<p>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 (200) connects a first encoder (230) to a second encoder (240) to perform encoding and thereby carry out LDPC-CC encoding, the first encoder (230) performing encoding based on an partial parity check matrix for information bits (110) obtained by extracting a sequence corresponding to the information bits in a parity check matrix (100) and the second encoder (240) performing encoding based on a partial parity check matrix for parity bits (120) obtained by extracting a sequence corresponding to the parity bits in the parity check matrix (100). A termination sequence generator (210) generates a termination sequence including the same number of bits as the memory length of the first encoder (230) and provides the generated termination sequence as an input sequence.</p> |
