ABSTRACT:
A co-channel interference canceler and a method therefor. The co-channel interference canceler includes: an NTSC interference rejection filter (NRF) for removing co-channel interference from an input signal; a noise reducer for reducing noise by removing interference other than co-channel interference from the input signal; and a selection controller for determining whether or not co-channel interference exists in the signal output from the noise-reducer and selecting the NRF when such co-channel interference exists in the noise reduced signal. Therefore, the effect from interference other than the co-channel interference is minimized, so that the co-channel interference controller is reliably controlled.
