Description

図３Ｃを参照して、別の１つのシンボル又は１シンボルの別の部分は、アンテナ、例えば、アンテナ２０８ａから、周波数Ｆ９を使用して送信された信号３３０、周波数Ｆ８を使用して送信された信号３３２、そして周波数Ｆ７を使用して送信された信号３３４を含む。このフレームのあいだ、周波数Ｆ７は、周波数帯域の最小周波数Ｆｍｉｎの近くであり、そしてそれゆえエミッション・マスク３００のエッジ領域３０２の近くである。したがって、信号３３４の、そしてそれゆえ信号３３０及び３３２の最大パワー・レベル３３６は、エミッション・マスク３００のエッジ領域３０２のパワー・レベルを超えないように減少される。減少量は、クリッピング及び／又はバック・オフによって与えられることができる。この送信フレームのあいだ、帯域外信号パワーは、エミッション・マスクの範囲内に維持され、そしてそれゆえ帯域外干渉は、許容可能な限界の範囲内である。
ホップ領域６００内で送信された任意のシンボルは、周波数帯域の最大キャリア周波数Ｓから距離Δ１であるＭの最大キャリア周波数、及び周波数帯域の最小キャリア周波数１から距離Δ２であるｉの最小キャリア周波数を有することができる。したがって、１つの実施形態ではバック・オフ及び／又はクリッピング・レベルは、Δ１及びΔ２に基づいて決定されることができる、又はある場合ではおそらくΔ１とΔ２のどちらかに基づいて決定されることができる。このアプローチは、モジュレータの出力のパワー・レベルに対するわずかな変更及び／又は複数のシンボル又はサンプルを備える個々の信号の個々のキャリア周波数に基づいてそれらのいずれか又は両方を変えるよりもクリッピング・レベルへのよりわずかな変更しか必要としない。
