Abstract

　送信パワー制御時間に制約がある場合においても、高精度に送信パワーを制御することができる送信パワー制御方法。パワーアンプのモードを切り換えるシンボル区間よりも前のシンボル区間において、モード切換前の前記パワーアンプの出力パワーを測定する第１の測定ステップと、前記第１の測定ステップで得られた測定結果と、送信パワー制御信号とに基づいて、モード切換後の前記パワーアンプのターゲットパワーを設定する第１の設定ステップと、前記パワーアンプのモードを切り換えるシンボル区間において、前記第１の設定ステップで設定されたターゲットパワーを用いて制御された、モード切換後の前記パワーアンプの出力パワーを測定する第２の測定ステップと、前記第２の測定ステップで得られた測定結果に基づいて、補正されたターゲットパワーを設定する第２の設定ステップとを含むようにした。
