Stealthy Signals: Using Ghost Modulation to Watermark Interference

Published: 06 October 2023 Publication History

Abstract

LEO satellite constellations have changed the world for the better through Earth observations, research, and telecommunications. Recent advances, especially in telecommunications, have brought the world closer to global connectivity. While these constellations usually have intra-network communications, they generally lack inter-network communication with other networks which leads to interference and noise. This interference and noise leads to degradation of network performance. We propose Ghost Modulation (GM), a novel protocol, to enable inter-network communication and spectrum coordination between a LEO satellite and any other device that supports the GM protocol. GM changes the transmission timing of key packets to encode data while passing most packets through. We evaluate our protocol and show that it can be used to dynamically coordinate heterogeneous networks with minimal overhead.
