Abstract
【解決手段】 送信機は、起動信号の後にパケットを複数回繰り返し送信する。受信機は、起動信号を検出するために第一の時間間隔で間欠受信動作し、起動信号を検出後は第二の時間間隔で上記パケットを検出することで受信機の消費電力を低減する。

Description
Claims (2)
- 不定期に送信されるデータを間欠的に受信するデータ通信システムにおいて、送信側は、送信の開始を示す起動信号と、前記起動信号に続いてパケットを複数回繰り返し送信し、受信側は、第一の時間間隔ごとに前記起動信号の間欠的検出を繰り返し、前記起動信号を検出したときは、第二の時間間隔ごとの間欠的受信によって前記繰り返し送信されるパケットの少なくとも1つを検出して、データを受信するデータ通信システム。
- 前記繰り返し送信されるパケットを第一のパケットとし、第一のパケットは、その後に送信される第二のパケットが送信されるタイミング情報を含み、このタイミング情報に基づいて第二のバケットを受信する請求項1のデータ通信システム。
