Description
こうした方法は、UMTS(Universal Mobile Telecommunication System:汎用移動通信システム)標準のシステムやある種の衛星通信で特に使用可能である。
第1の計算器αは前のデータを用いて結果データを計算する。
第2の計算器βは次のデータを用いて結果データを計算する。
第3計算器λは第1および第2計算器の結果と入力データとを用いて結果データを計算する。
−前のデータウィンドウを書き込む第2アドレス方向とは反対の方向の第1アドレス方向に現在のデータウィンドウを固有のバッファに書き込み、前のデータウィンドウのデータが書き込まれていないアドレスから前記現在のデータウィンドウの書込みがはじまり、前記バッファの長さがデータウィンドウの最大サイズよりも大きいステップと、
−前記前のデータウィンドウの最後の書込みアドレスに等しい読取りアドレスから、前記固有のバッファからの前記前のデータウィンドウのデータを読み取り、前記読取りが現在のデータウィンドウの前記書込みと同時に同じ第1アドレス方向に実行されるステップと、を含む方法が提供される。
