Wireless communications 'N + 1 dimensionality' endogenous anti-jamming: theory and techniques

The existing theory and techniques of wireless communication anti-jamming have reached their performance limit recently. With this focus, by leveraging the inherent characteristics of wireless communication and referring to the principle of cyberspace endogenous security, this paper investigates the core issues of endogenous security in the electromagnetic space, namely, endogenous anti-jamming (EAJ), which can defend against unknown electromagnetic attacks effectively. Specifically, the subspace method is first adopted to establish the unified framework for the conventional spread-spectrum, intelligent, and endogenous anti-jamming, in which both the intrinsic development law of each technique and the internal logic between them are revealed. Then, the fundamental concept, key techniques, and development suggestions of wireless communication “N + 1 dimensionality” endogenous anti-jamming are proposed to seek a disruptive breakthrough.
