Patent number: 8855592Abstract: 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.Type: GrantFiled: May 27, 2008Date of Patent: October 7, 2014Assignee: Intel CorporationInventors: Andrey V Belogolovy, Mikhail Lyakh, Alan E. Waltho, Anu Hannele Huttunen, Risto Kaunisto

Patent number: 8451962Abstract: In some embodiments a method is disclosed for detecting periodic interference and predicting future interference times. The method can include detecting an arrival time of a first occurrence of interference and detecting an arrival time of a second occurrence of interference. The method can include transmitting preemptive interference mitigation control signals that anticipate future arrival times of interference. A system is disclosed that includes a periodicity detector, an interference profiler and a mitigation control module. The system can provide interference mitigation features to a data recovery system. Other embodiments are disclosed.Type: GrantFiled: May 27, 2008Date of Patent: May 28, 2013Assignee: Intel CorporationInventors: Andrey V Belogolovy, Mikhail Lyakh, Alan E.

Patent number: 8199862Abstract: A method is disclosed for interference mitigation which can include receiving a signal having a data component, an interfering component and a time period and creating a first plurality of digitized data that represents at least a portion of the interfering component. The method can also include generating a polynomial equation that is related to the at least a portion of the interfering component and generating a second plurality of digital data that represents a data vector of the received signal. The method can further subtract the polynomial equation from the received signal to cancel at least a portion of the interfering component to provide an interference mitigated signal representing the data component.Type: GrantFiled: May 27, 2008Date of Patent: June 12, 2012Assignee: Intel CorporationInventors: Andrey V Belogolovy, Mikhail Lyakh, Alan E.

Patent number: 8199856Abstract: 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.Type: GrantFiled: May 27, 2008Date of Patent: June 12, 2012Assignee: Intel CorporationInventors: Andrey V Belogolovy, Mikhail Lyakh, Alan E.
