Abstract:
A co-channel interference cancelling system comprising:a co-channel interference rejection filter for performing co-channel interference rejection filtering on a first signal having co-channel interference and outputting a second signal;a selection signal generator for generating a selection signal, said selection signal generator calculating a first error corresponding to said first signal and a second error corresponding to said second signal, said first error and second error being based on a reference signal, said selection signal being one of the first signal and second signal having a lesser error;a selection corrector for correcting the selection signal and outputting a corrected selection signal such that a predetermined one of the first signal and the second signal is selected when the first error and the second error is within a predetermined range; anda selector for selecting one of the first signal and second signal based on the corrected selection signal.
