Conservative but Stable: A SARSA-Based Algorithm for Random Pulse Jamming in the Time Domain

Abstract

As a dynamic jamming pattern, random pulse jamming is stochastic, sudden, and not easily perceived or addressed. Random pulse jamming can exert a negative influence on the quality of wireless communication. This paper models an anti-jamming communication under random pulse jamming as a Markov Decision Process and proposes a SARSA-based Time-domain Anti-jamming Algorithm (STAA). Differently from previous research, this study attempts to use the SARSA algorithm to counter random pulse jamming in the time domain. The proposed STAA can achieve high-quality transmission while maintaining small fluctuations in transmission performance when the risk of external interference is high.
