abstract = "In this paper, we first analyze how a jamming signal applied through arbitrary frequencies within the band can affect the entire band in orthogonal frequency division multiplexing (OFDM) communication systems. Then, we propose an anti-jamming technique based on joint maximum likelihood (JML) detection that can effectively mitigate the effects of OFDM jamming signals in legitimate transmitter and receiver links for all sub-carriers. In addition, in this paper, we theoretically analyze the performance of the proposed JML detector-based anti-jamming technique. Through extensive simulations, we verify the improvement of the anti-jamming performance for the proposed technique and the accuracy of our analysis results."
