Abstract

　サーキュラバッファにおける読出し開始アドレスおよび読出し方向の最適な選択基準を用いて復号性能を向上させることができる無線通信装置。この装置において、インタレース部（１３）は、インタリーブおよびインタレースされたビット系列をサーキュラバッファ（１４）に書き込み、ＲＶ決定部（１０９）は、未送信システマティックビット数、未送信重要パリティビット数および／または未送信非重要パリティビット数に基づいてサーキュラバッファ（１４）の読出し開始アドレスと読出し方向を決定し、読出し制御部（１１０）は、サーキュラバッファ（１４）の読出し開始アドレスおよび読出し終了アドレスを制御し、読出し部（１５）は、読出し制御部（１１０）の制御に従って、サーキュラバッファ（１４）から符号化ビットを連続的に読み出す。
