Abstract
A co-channel interference canceler and a method thereof. The co-channel interference canceler comprises: a co-channel interference rejection filter for outputting a second signal by performing co-channel interference rejection filtering on a first signal including co-channel interference; a selection signal generator for generating a selection signal which selects the signal with less error by calculating the error of each of the first and second signals with respect to a reference signal; a selection corrector for outputting a corrected selection signal by correcting the selection signal such that a predetermined one of the first and second signals is selected in a predetermined error region; and a selector for selecting one of the first and second signals according to the corrected selection signal. Therefore, unlike the selection signal whose state is easily changed even when the channel condition changes only slightly, the selection signal for driving the NRF is maintained in a predetermined error region to select a predetermined path, thereby improving stability and performance of the system.
