Abstract
An encoding processing apparatus in which reception precision characteristics are improved by specially adapting puncture processing in respect of the code words for each encoding system. A puncture section switches between a puncture pattern for a first code word partial sequence obtained on the basis of the head and tail in a fixed information block, and a puncture pattern for a second code word partial sequence obtained on the basis of the middle portion, excluding the head and tail. Also, the puncture section receives the number of retransmissions of information from a retransmission control section and switches the puncture pattern for the second code word partial sequence in accordance with the number of retransmissions. In addition, the puncture section prioritizing systematic bits over parity bits when puncturing the first code word partial sequence.
