Abstract :
A performance analysis is presented for a coded FH/MFSK (frequency-hopping/M-ary frequency-shift-keying) system under a combination of tone jamming and full-band-noise jamming (FBNJ). A maximum likelihood metric former with Viterbi´s ratio threshold techniques is assumed to support the decoder in the system. It is shown that the most efficient FBNJ portion of the total jamming power depends on M and the symbol energy-to-jamming power density ratio
