IPC: H04B7/26
Filed: 1980-03-27
Abstract: PURPOSE:To receive a signal without hindrance in case of communication from a mobile radio station, etc., by providing a comparing circuit which discriminates by a comparison whether a transmitted modulation signal and received demodulation signal coincide with each other. CONSTITUTION:When a signal is transmitted from signal generator 4 by radio device A2A, a signal from signal line 5 is discriminated by discriminating circuit A16A and antenna change-over contact A13A is placed at the transmission side to emit a radio wave from transmitter A11A. At this time, overreaching is done, the radio wave of device A2A is received and demodulated by receiver B14B of radio device B2B, and comparing circuit B20B compares the output of modulated signal amplifier B10B with that of receiver B14B, so that both the outputs will be found coinciding with each other. For this purpose, relay contact B21B is opened to prevent the received demodulated output from reaching central controller 1, thereby preventing the overreaching. If a radio wave from mobile radio device 3 is received by receiver B14B, on the other hand, contact B21B is closed since two inputs to circuit B20B are different, so that the demodulated signal received from device 3 is transmitted to device 1 via received signal line 7.
