Title: 複数のユーザチャネルに対してｐｎシーケンスを発生する電気通信システムにおける送信機、受信機および方法
IPC: H04L1/24
Filed: 1999-08-24
Abstract: (57)【要約】
複数のユーザチャネルがタイムスロット方式で処理される電気通信システムにおいて、送信機および受信機は、１つのＰＮ発生器（Ｔ−ＰＮ）および１つの状態メモリ（ＩＳＭ）を使用するだけで、複数のユーザチャネルに対するビットエラーレート測定を実施することができる。状態メモリ（ＩＳＭ）に対して読み書きするためにリード／ライト手段（Ｒ／Ｗ）が設けられる。タイミング手段（ＴＭ）が新しいタイムスロットの始まりを検出するときは常に、リード／ライト手段（Ｒ／Ｗ）が状態メモリ（ＩＳＭ）から最後に格納された位相状態を読み出す。各タイムスロットの終りを検出すると、そのときにＰＮ発生器（Ｔ−ＰＮ）に存在する位相状態が状態メモリ（ＩＳＭ）に格納されて、後続フレーム内の同じタイムスロットに対するＰＮ発生器（Ｔ−ＰＮ）の再初期化に使用される。したがって、多数のユーザチャネルに対してＰＮシーケンスを発生するのに１つのＰＮ発生器（Ｔ−ＰＮ）で十分である。
