With the advancement of Artificial Intelligence (AI) and Explainable AI (XAI), Deep Learning (DL) algorithms become increasingly vulnerable to adversarial machine learning (AML) threats. One of the widely used DL-based applications in wireless communication is the Automatic Modulation Classification (AMC). In this paper, we investigate XAI methods for designing AML attacks in DL-based AMC systems. Specifically, we discuss four AML tactics, namely, untargeted causative, targeted evasion, untarget
