Abstract

An encoder and decoder using LDPC-CC which avoid lowering the transmission efficiency of information while not deteriorating error correction performance, even at termination; and an encoding method of the same. A termination sequence length determining unit determines the sequence length of a termination sequence transmitted added to the end of an information sequence, according to the information length (information size) and encoding rate of the information sequence. A parity calculation unit carries out LDPC-CC coding on the information sequence and the known-information sequence necessary for generating a termination sequence of the determined termination sequence length, and calculates a parity sequence.

First claim

The invention claimed is:

1. A transmission apparatus comprising:
a calculating section that calculates parity bits by encoding an information sequence, made up of a plurality of bits, and known information to be added to the information sequence, using a low density parity check convolutional code (LDPC-CC);
an outputting section that outputs the information sequence and the parity bits;
a determining section that determines a sequence length of a parity sequence according to…
