IPC: H04B1/709
Filed: 2000-06-13
Abstract: An optimum combiner that reduces the amount of interference imposed upon a first base station (102) by transmissions of other base stations within the same communication system. Two antennas (112, 114) are used to receive transmissions within a receiving station (110). A rake receiver is coupled to each antenna (112, 114). By optimally combining the signals that are received by each independent finger of the rake receiver, interference that is correlated between a finger associated with the first antenna (112) and a finger associated with the second antenna (114) can be minimized with respect to the desired signal. Optimum combining requires determination of optimum combining coefficients. A max-ratio combining algorithm may be substituted for the optimal combining algorithm depending upon interference characteristics.

Abstract: (57)【要約】
判定フィードバック等化器と合同での動作に適した単純で強固なボー・レート・タイミング復元のためのシステムと方法を開示している。タイミング復元のためのタイミング関数は、フィードフォワード・フィルタ及びフィードバック・フィルタのフィルタ係数のみから抽出される。フィードバック・フィルタの係数とインパルス応答の関係が分かることで、フィードフォワード・フィルタの係数とインパルス応答の関係は、ゼロフォーシング状態のもとで導かれる。この関係に基づくと、様々な計算の程度のいくつかのタイミング関数が導かれ、およそチャンネルインパルス応答のピークポイントでサンプリング例を生じる。導かれたタイミング関数が等化係数を使用するので、これらは、トレーニング・シーケンスを使用することなく等化と共に機能する。１２５Ｍボーの５ｍと１００ｍのＵＴＰカテゴリー５のケーブルによるシミュレーションの結果がフェーズロックループにおける素早く強固なタイミング復元動作を示す。
