ABSTRACT:
A co-channel interference canceler and a method therefor. The co-channel interference canceler includes: a co-channel interference rejection filter for outputting a second input signal by removing co-channel interference from a first input signal; a first post processor for removing interference other than co-channel interference from the second input signal; a second post processor for removing interference other than co-channel interference from the first input signal; and a selection controller for selecting the output of the post processor which has less error by comparing the output of the first post processor with the output of the second post processor. Therefore, other interference such as ghost and phase noise included in an input signal are removed or reduced via the extra second post processor which is different from the first post processor of the signal path. The selection of the NRF is controlled using the signal from which other interference has been removed or decreased, thereby minimizing the effects of the other interference. As a result, error in selection of the NRF, which may be caused by the other interference, can be prevented, and selection of the NRF is reliably controlled.
