Novel Narrowband Interference Model to Analyze the Electromagnetic Resilience of OFDM Systems

Orthogonal Frequency Division Multiplexing based protocols are increasing in popularity for use in applications where dependability under harsh Electromagnetic conditions are of major importance, for example Vehicle-to-Everything communication. Orthogonal Frequency Division Multiplexing is especially vulnerable to narrowband interferences and thus, evaluating the electromagnetic resilience of Orthogonal Frequency Division Multiplexing systems to narrowband interferences is particularly interesting and important. Current narrowband interference models either don’t take into account the bandwidth of the narrowband interference or are constructed in such a way that in depth analysis on short time scales is impossible. Therefore, this paper presents a novel narrowband interference model for electromagnetic resilience analysis without the aforementioned limitations. The model is mathematically defined, a mathematical derivation for the interference spectrum is given and simulations for the model are performed when it behaves as a QAM16 interferer.
