    • A reception amplifier failure detecting device includes an antenna sharing unit, a reception amplifier, a receiver, an electric field detecting section, a transmitter, a power control section, and a failure detecting section. The antenna sharing unit demultiplexes a transmission signal from a transmission system to an antenna and a reception signal from the antenna to a reception system. The reception amplifier amplifies the reception signal. The receiver receives an output signal from the reception amplifier. The electric field detecting section detects the electric field strength of a signal received by the receiver. The transmitter outputs a transmission signal to the antenna via the antenna sharing unit. The power control section controls the transmission power of the transmitter on the basis of a standard transmission value, and outputs transmission power information. The failure detecting section performs failure determination by comparing the electric field strength information with a failure detection reference value set on the basis of a standard attenuation value, a standard amplification value of the reception amplification means, and the transmission power information of the transmission means. A reception amplifier failure detecting method is also disclosed.

    • A base station (202) receives, from mobile stations (2031-203N), notifications of transmission and reception powers thereof, which are input to a failure detecting part (218) together with the information about transmission and reception powers of the main device for the mobile stations. The failure detecting part (218) obtains upstream and downstream propagation losses of each one of propagation paths (2041-204N). When the difference between those losses exceeds a predetermined tolerance, the failure detecting part (218) determines, based on such an exceeding difference, which one of the transmitters or receivers has a failure. In this way, there is no need to provide any special circuit for detecting a failure of a transmitter or receiver.
