Abstract
A multi-tone jammer mitigation method includes: obtaining, wirelessly at an apparatus, a first jammer signal with a first frequency; obtaining, wirelessly at the apparatus, a second jammer signal with a second frequency; determining at the apparatus that the first jammer signal and the second jammer signal comprise a multi-tone jammer; and inhibiting, at the apparatus based on the first jammer signal and the second jammer signal comprising the multi-tone jammer, processing of the first jammer signal by the apparatus.
Claims16
An apparatus comprising:
- one or more receivers configured to obtain, wirelessly, a first jammer signal with a first frequency, and configured to obtain, wirelessly, a second jammer signal with a second frequency;
- one or more processors, communicatively coupled to the one or more receivers;
- and
- one or more adjustable filters communicatively coupled to the one or more processors and configured to inhibit signals of a selectable frequency from reaching the one or more processors;
- wherein the one or more processors are configured to:
- determine that the first jammer signal and the second jammer signal comprise a multi-tone jammer;
- and
- inhibit, based on the first jammer signal and the second jammer signal comprising the multi-tone jammer, processing of the first jammer signal by the one or more processors by controlling the one or more adjustable filters to set the selectable frequency to the first frequency, wherein the one or more receivers are configured to obtain, wirelessly, a third jammer signal with a third frequency, and the one or more processors are configured to inhibit processing of the first jammer signal over inhibiting processing of the third jammer signal based on the multi-tone jammer exceeding a first tolerance level by more than the third jammer signal exceeds a second tolerance level.
