Effects of composite PBNJ and MTJ on FFH/MFSK systems with maximum-likelihood receiver over frequency-selective fading channels

The performance of a fast frequency-hopped M-ary frequency-shift-keying system with maximum-likelihood (ML) receiver under the composite effect of partial-band noise jamming and multitone jamming (MTJ) over frequency-selective Rayleigh fading channels is investigated in this paper. Both the desired signal and the MTJ are assumed to experience independent frequency-selective Rayleigh fading. Analytical bit-error rate expressions for the ML receiver are derived and validated by computer simulation. The proposed ML receiver is shown to suppress interference more effectively than the other existing diversity-combining receivers.
