A base station includes antennas, a local signal generator; first and second mixers generating first and second mixed signals by mixing first and second signals from first and second antenna among the antennas and the local signal; first and second analog digital converters converting to first and second digital signals, first and second interference detecting units detecting first and second interference signals based on the first and second digital signals; first and second interference removing units generating first and second processed signals by removing the first and second interference signals by first and second filters having first and second filter central frequencies shifted in first and second directions from first and second interference central frequencies of the first and second interference signals, respectively; and a combining unit combining the first and second processed signals. |
