Abstract: Aspects of the subject disclosure may include, for example, obtaining a schedule of spectral segments in a communication link of a communication system. Signal interference is identified in a portion of a number of spectral segments according to the schedule of spectral segments and at least one threshold for detecting interference. A determination is made that a number of signal interferers in the portion of the number of spectral segments exceeds a number of filters and, responsive to the number of signal interferers exceeding the number of filters, use of the number of filters is prioritized to filter signal interference in the portion of the number of spectral segments for suppressing at least a portion of the signal interference detected.

Abstract: A system that incorporates the subject disclosure may include, for example, a process that includes adjusting a filter in electrical communication between an input terminal and a demodulator. The filter is applied to an information bearing signal, e.g., to mitigate interference, received at the input terminal, resulting in a filtered signal. An error signal is received, indicative of errors detected within information obtained by demodulation of a modulated carrier of the filtered signal. A modified filter state is determined in response to the error signal and the filter is adjusted according to the modified filter state, e.g., to improve mitigation of the interference. Other embodiments are disclosed.
