Abstract: いかなるトレーニング信号も復調された情報シンボルも必要としない繰り返しのブラインド周波数オフセット推定処理が開示される。最大尤度の意味で受信信号に最良に適合する周波数オフセットの推定値を見つけるために、いくつかの実施形態では、開示される処理を具現化する受信機は、計算上集中的である等化または復調のアルゴリズムを実行することなく、時間領域内の受信信号の時間的な相関、および同相および直交位相の次元にわたる受信信号の相関を用いることにより、周期的な周波数オフセットの推定値を生成できる。受信周波数オフセットを推定する例示的な方法では、時間的にスタックされた信号ブロックが、受信信号の２つ以上の時間的に分離されたサンプルの各々に対応するマルチブランチの信号サンプルから形成される。時間的にスタックされた信号ブロックは、受信周波数オフセットおよび当該受信周波数オフセットの分だけ逆回転された時間的にスタックされた信号ブロックの空間共分散の最尤同時推定値の計算に用いられる。 【選択図】図３
