PURPOSE: An ICS(Interference Canceller System) is provided to create filter coefficients every frequency, and to separate interference signals by using the created filter coefficients, thereby extracting exact frequency information by increasing response speed and reducing system instability as preventing the interference signals. CONSTITUTION: An LPF(Low Pass Filter)(200) passes signals only less than a center frequency among inputted signals of time regions, and outputs the passed signals to a windowing units(204,210). An HPF(High Pass Filter)(202) passes signals only more than the center frequency among the inputted signals, and outputs the passed signals to the windowing units(204,210). A filter coefficient generator(216) adds two frequency bands into one, and generates filter coefficient every frequency by using an adaptive algorithm. A digital filter(220) separates interference signals by using the generated filter coefficients.
