Interference mitigation techniques for air to ground systems

摘要

A method for air to ground communication interference mitigation within an aircraft equipped with a multi-beam array antenna includes adjusting a modulation symbol interleaving and/or forward error correction of an aircraft receiver interface in response to detected interference from an interferer. The method further includes reducing a data rate of the aircraft receiver interface when the adjusting of the modulation symbol interleaving and/or forward error correction does not mitigate the detected interference. Another method for interference mitigation may include performing antenna beam-steering away from a geographic (GEO) arc during an aircraft turn. This method further includes reducing an aircraft transmitter transmit power when a signal quality of a forward link is within a predetermined range of a signal quality threshold.

1. A method for air to ground communication interference mitigation within an aircraft equipped with a multi-beam array antenna, comprising:
adjusting a modulation symbol interleaving and/or forward error correction of an aircraft receiver interface in response to detected interference from a forward link of an interferer aircraft; reducing a data rate of the aircraft receiver interface when the adjusting of the modulation symbol interleaving and/or forward error correction does not mitigate the detected interference, from the forward link of the interferer aircraft, on communications received by the aircraft receiver interface from a serving ground station through the multi-beam array antenna; and providing aircraft internet service based on the communications received by the aircraft receiver interface from the serving ground station through the multi-beam array antenna.
