Abstract

　本発明の通信システムは、送信装置及び受信装置を備える。前記送信装置は、所定周波数の信号の送信を行う送信手段と；所定の情報を含む第１の信号と、この第１の信号の送信先となる前記受信装置を特定するための識別情報を含む信号であってかつ、この信号の解析に要する処理量が前記第１の信号よりも小さい第２の信号とを、前記送信手段を介して送信する送信制御手段と；を備える。前記受信装置は、前記所定周波数の信号の有無の検出、及び、この所定周波数の信号の受信を行う受信手段と；この受信手段によって前記所定周波数の信号が検出された場合に、前記受信手段に第１の時間だけ、この所定周波数の信号を受信させ、前記受信手段が受信した信号に前記第２の信号が含まれているか否かを判定し、この第２の信号が含まれていた場合に、前記受信手段に、前記第１の時間よりも長い第２の時間だけ前記所定周波数の信号を受信させる受信制御手段と；を備える。
