Abstract
Description
Claims (1)
- 【特許請求の範囲】 1.複数の受信チャネルのうちの一つの制御チャネルを識別するために設けられ た、前記受信チャネルの出力(Pr)を測定する手段(3)と、リスト(5)中 で識別されたチャネルの少なくともいくつかに同期を試みる手段(4)とを具備 する、無線通信システムの端末用の同期装置において、出力(Pr)を有する基 準チャネル(Cr)がそのi番目の先行チャネル(Cr-i)及びi番目の後続チャ ネル(Cr+i)に対してi次の減衰(Ai)を有するように前記システムが定義さ れ、前記のi番目の先行チャネル(Cr-i)又は前記のi番目の後続チャネル( Cr+i)が、その出力がi次の減衰(Ai)で低下した基準チャネル(Cr)の出 力(Pr)より低い場合にはリスト中に現れないようにする選択手段を具備する ことを特徴とする同期装置。
