PURPOSE:To realize one frequency system by removing a transmitting interference by means of adaptable control technics. CONSTITUTION:An adder 83 is provided which adds the first and second filters 5 and 5' to filter respectively the signal after identifying the first and second digital modulating waves 203 and 203', the third and fourth filters 6 and 6' to filter respectively the signal after identifying the fifth and sixth digital modulating waves 201 and 201', the signal before identifying the fifth modulating wave and the output of the first fourth filters 5, 5' and 6, 6'. From the adder 83, the fifth modulating wave can be obtained in which the transmitting interference from both orthogonal polarized waves from the first and second transmitting ports is removed. |
