Narrowband jamming Mitigation in OFDM Systems Using Time Domain Interleaving

In this paper, Time Domain Interleaving (TDI) is proposed to mitigate narrowband jamming in orthogonal frequency division multiplexing (OFDM) systems. TDI is previously used as a physical layer security technique against eavesdropping attacks. In this work, TDI ability to reject narrowband jamming is demonstrated and evaluated in additive white Gaussian noise (AWGN) with Rayleigh fading. Different narrowband jamming scenarios are considered with different numbers and locations of jammed subcarriers. The obtained results show that TDI significantly improves the bit error rate (BER) performance of OFDM under narrowband jamming.
