Abstract A Differential Jamming Rejection (DJR) receiver in FFH/MFSK systems is introduced under a worst-case band multi-tone jamming. This method, based on ahead spectrum detection using apriority knowledge of FHP (Frequency Hopping Pattern) and FH rate, implements differential suppression of multi-tone jamming without any side information. Further analysis and data simulation indicate that this scheme possesses good efficiency.
