Abstract

PURPOSE:To remarkably reduce the probability causing communication impossibility due to disturbance, by constituting so that an output of an AGC circuit, received by a subantenna whose amplitude and phase have been controlled is subtracted from an output of the AGC circuit received by a main antenna. CONSTITUTION:A desired wave S1 and a disturbing wave X1, received by a main antenna 1, and a desired wave S2 and a disturbing wave X2, received by a subantenna 2 are provided to receiving frequency converting parts 4 and 5. An intermediate frequency outputs s1+x1 and s2+x2, outputted from the converting parts 4 and 5 are provided to AGC circuits 7 and 8, respectively. An output of the circuit 7 is provided to a subtracting circuit 9. On the other hand, as for an output of the circuit, its amplitude and phase are controlled by a control signal (a) in an amplitude and phase controlling circuit 10, and after that, said output is subtracted from the output of the circuit 7 in the circuit 9. In this way, the output of the circuit 7 is demodulated by a demodulating part 11 after the disturbing wave has been rejected. In this regard, a disturbing wave reproducing part 12 reproduces a disturbing wave contained in an output of the demodulating part 11, and provides it to a correlation operating part 13. The operating part 13 detects correlation of outputs of the circuit 8 and the reproducing part 12, and generates the signal (a).
