Abstract
A co-channel interference canceling system that uses adaptive filters exploiting the short-term spectral symmetry of narrow-band FM signals. The carrier frequency of a signal-of-interest is designated. An adaptive filter is generated that passes those spectral components that exhibit symmetry about this center-point frequency, and attenuates those that do not. Co-channel interferers detuned from the SOI are significantly attenuated, greatly improving the reception of the signal of interest.
