Anti-Jamming Randomized OFDM Band Hopping for Tactical Communications
Orthogonal frequency division multiplexing (OFDM) is proved to be a robust well-known technique and
hopping across various frequency bands is also known for its ability to enhance the system's performance. Combining both
of them should be beneficial in mitigating interference and jamming caused accidentally or on purpose especially in military
applications. In this paper, the bit error rate (BER) performances of an improved OFDM communication system utilizing
different frequency band hopping techniques against diverse types of jammers are presented. The overall system
performance is improved gradually by increasing the number of frequency hopping bands against narrowband, wideband,
and barrage jammers in case of low jamming power at the receiver front end. At high jamming power, no improvement is
achieved using band hopping.
