Abstract

　コード多重される応答信号の分離特性の劣化を最小限に抑えることができる無線通信装置。この装置において、制御部（２０９）は、判定部（２０８）から入力されたＰＵＣＣＨ番号に基づいて、拡散部（２１４）での１次拡散に用いるＺＣ系列の循環シフト量および拡散部（２１７）での２次拡散に用いるウォルシュ系列を制御し、拡散部（２１４）は、制御部（２０９）によって設定されたＺＣ系列で応答信号を１次拡散し、拡散部（２１７）は、制御部（２０９）によって設定されたウォルシュ系列で応答信号を２次拡散する。拡散部（２１７）は、同一循環シフト量において互いに異なる移動局で使用される複数のウォルシュ系列のうちウォルシュ系列長より短い系列長で互いに直交するいずれかのウォルシュ系列を用いて応答信号を２次拡散する。
