The composite effect of hostile multitone jamming and partial-band noise jamming on bit-error rate (BER) performance of a fast frequency-hopped -ary frequency-shift-keying system is studied over Rayleigh fading channels in the presence of timing and frequency offsets. The maximum-likelihood (ML) diversity-combining method is employed to improve BER performance of the system. Analytical BER expression...
Based on the likelihood ratio, we derive the maximum-likelihood (ML) receiver for a synchronous fast frequency-hopped multiple-access system employing M-ary frequency-shift-keying (MFSK) modulation over frequency-selective Rayleigh-fading channels. The derived ML receiver is proposed and analyzed to obtain bit-error rate (BER) expressions. Analytical results are then validated by computer simulations...
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...
