Abstract

In this paper, a differential jamming rejection (DJR) receiver in fast frequency hopping (FFH) M-ary frequency shift keying (MFSK) systems with a worst-case band multitone jamming (MTJ) is introduced. This receiver, based on detecting frequency spectrum difference in forward-backward time slot while the FFH/MFSK signal arrive receiver, implements differential suppression of a worst-case band multitone jamming without any side information. Further analysis and data simulation indicate that this scheme possesses good efficiency.
