Performance analysis of an FFH/BFSK self-normalising receiver under multitone jamming

Analytical expressions for bit-error probability are derived for a fast fre quency-hopping binary frequency-shift-keying (FFH/BFSK) spread-spectrum (SS ) communication system based on Taylor-series expansion. The FFH system emp loys soft-decision self-normalising receiver against the worst-case multito ne jamming (MTJ) and additive white Gaussian noise (AWGN). The authors' ana lysis, validated by the simulation results, shows that the band MTJ is gene rally more harmful than the corresponding independent MTJ. Unlike the soft- decision linear-combining receiver, the worst-case partial-band jamming (PB J) causes slightly poorer bit-error-rate (BER) performance than the corresp onding worst-case band MTJ for the self-normalising receiver with diversity . The BER performance of the self-normalising receiver is shown to be signi ficantly better than that of the soft-decision linear-combining receiver un der the conditions of the worst-case band MTJ and AWGN.
