Abstract: A method is disclosed for mitigating narrowband interference within a system for wideband communications. The method can include separating a wideband signal into a plurality of sub bands, detecting energy levels in the sub-bands, and activating a control signal if the energy levels of the sub-bands differ by a predetermined amount. Such a difference in energy levels can indicate that narrowband interference is present and interference mitigation features can be activated. In another embodiment, a system is disclosed that has a band splitter and a plurality of energy level detectors to detect energy differences in the sub bands. Other embodiments are also disclosed.

Abstract: A method is disclosed that includes receiving a signal having a data vector component and an interfering component and creating a first set of digitized data that represents the interfering component. The method can also generate a polynomial equation based on the first set of digitized data and generate a second set of digitized data that represents a data vector component of the received signal. The polynomial equation can be subtracted from the received signal to cancel at least a portion of the interfering component and provide an interference mitigated signal representing the data vector component. An error in the interference mitigated signal can be determined and the interference mitigated component can be recalculated based on the error. Other embodiments are also disclosed.
