Abstract

This work considers the bit error rate (BER) performance of orthogonal frequency division multiplexing (OFDM) frequency hopping (FH) systems in the presence of Multitone jamming (MTJ) and multipath fading. Analytical and simulation results confirmed that optimum jamming strategies require channel and signal power side information. Moreover, the common assumption that the jamming tones and subcarriers frequencies are identical can be quite inaccurate at low signal-to-jamming power ratios (SJR), particularly for small number of jamming tones.
