Transmitting/receiving system and medical system

摘要

A transmitting/receiving system includes a transmitting apparatus (2, 72) that generate modulated signals each containing a broadband signal component and a narrowband signal component, and transmits the modulated signals to the outside; and a receiving device (3; 53; 63; 83) that receives the modulated signals via at least three receiving antennas. The receiving device (3; 53; 63; 83) includes a signal processing system (41; 51; 61) that processes the broadband signal component contained in the modulated signal; and a received-strength detecting system (40; 50; 60) that processes the narrowband signal component contained in the modulated signal.
