Physical‐layer intrusion detection system for smart jamming attacks

摘要: In modern electronic warfare, physical-layer security threats have evolved from traditional jammers to smart jammers. Smart jammers, due their stealthy nature, make wireless communication systems vulnerable. They can easily deceive a detection system. this paper, intrusion system (PLIDS) for direct-sequence spread-spectrum is developed against which efficient its high rates, usability, and accuracy. jamming noise modeled as wide-sense stationary, additive, colored. This random process decomposed into series expansion of independent uncorrelated variables. The decomposition helps in designing signal processing algorithm PLIDS. implemented via correlators. PLIDS evaluated using simulated warfare environment, performance measured terms capability, precision, It performs error-free by adjusting tuning parameter. Moreover, different tradeoffs are observed values the Finally, comparisons done with competitive systems.
