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.

Abstract: A system that incorporates the subject disclosure may perform, for example, a method that determines at least one threshold for detecting signal interference in a first plurality of segments occurring in a first radio frequency spectrum of a first wireless communication system, detecting a pattern of recurrence over time of signal interference in a segment of the first plurality of resource blocks according to the at least one threshold, and performing one or more mitigation steps to mitigate the signal interference without filtering the signal interference where the one or more mitigation steps include at least one of transmitting signals out of phase from the signal interference, adjusting transmit power, increasing power in a resource block of a long term evolution communication session, performing beam steering, or changing time parameters for the resource block without changing to a new resource block. Other embodiments are disclosed.
