Description
2)高域通過フィルタ補償(HPFC)モジュール310
3)オプションのDCオフセット機能を伴う正規化補償モジュール315
4)タイムドメイン(time domain)補償モジュール320
5)自動位相アンバランス補償(APIC)モジュール325
6)自動振幅アンバランス補償(AAIC)モジュール330
7)低ノイズ増幅器(LNA)位相補償モジュール335
受信機DBB補償プロセッサ125を使用すると、アナログ無線受信機105のコンポーネントのRF要件が緩和され、使用するコンポーネントのコストと電力消費が削減される。RFコンポーネントの許容誤差による障害は、オールデジタルゲイン制御(ADGC:all digital gain control)コンポーネントを使用することで修正され、アナログ無線受信機105のいかなるコンポーネントも調整する必要はない。
2)振幅アンバランス補償モジュール510
3)位相アンバランス補償モジュール515
4)DCオフセット補償モジュール520
プリディストーション補償モジュール505は、振幅変調(AM:amplitude modulation)から位相変調(PM:phase modulation)への信号特性およびPM−AM信号特性など、送信の振幅特性を修正するために使用する。アナログ無線送信機445に含まれるパワー増幅器460の振幅特性と位相特性が特定される。ここで、プリディストーション補償モジュール505は、入力レベルを確認する。プリディストーション補償モジュール505は、パワー増幅器が線形の応答を生成するように、パワー増幅器460のゲイン特性と位相特性に基づいて、I信号とQ信号の位相と振幅に意図的に歪みを加える。プリディストーション補償モジュール505は、LUTまたは同様のものを参照し、こうした振幅特性を取得することができる。本発明のこの実施形態の利点は、アナログ無線送信機445に安価で品質の低いコンポーネント(例えば、定格出力の低い増幅器)を使用した場合でも、相互変調歪みなどのパラメータの標準を満足することである。
