1. An apparatus comprising processing circuitry configured to:
- receive information indicative of a local interferer, the local interferer being identified based on dynamic position information indicative of a position of an aircraft;
perform noise cancellation relative to a received signal by removing an interference signal associated with the local interferer to generate a scrubbed signal; and
provide the scrubbed signal for additional signal processing,wherein receiving information indicative of the local interferer comprises receiving the information indicative of the local interferer in advance of the aircraft being in a cell in which the local interferer is located, andwherein performing noise cancellation relative to the received signal comprises employing a noise cancellation technique selected from among a plurality of different noise cancelation technique options in advance of the aircraft being in the cell in which the local interferer is located.
