PURPOSE:To simultaneously and efficiently transmit and receive radio waves without an influence of the interference wave due to trespassing of a radio wave by generating an artificial leaked wave and subtracting it from an actual leaked wave. CONSTITUTION:The above equipment consists of a reception antenna 1, a receiver 3, a control circuit 8 for reception processing and transmission control, a transmitter 9, a circuit 11 which simulates the transmission characteristic of the route, through which a radio wave passes a transmission antenna 10 from the transmitter 9 and is leaked to the reception antenna 1 and is received by the receiver, to generate the artificial leaked wave, and a circuit 12 which operates the difference between the signal received through the reception antenna 1 and the signal generated by the artificial leaked wave generating circuit 11. The difference between the signal actually leaked from the transmission system to the reception system and the artificial leaked signal generated by simulation in the equipment is obtained to eliminate an influence of the leaked signal. Thus, transmission and reception are simultaneously and efficiently performed without an influence of the interference wave due to trespassing of a radio wave. |
