Multitone jamming rejection of FFH/BFSK self-normalizing receiver
A computationally efficient bit-error rate (BER) expression for a fast frequency-hopped binary frequency shift-keying (FFH/BFSK) spread-spectrum (SS) communication system is derived based on Taylor-series expansion. The FFH system employs a soft-decision self-normalizing receiver against the worst-case multitone jamming (MTJ) and additive white Gaussian noise (AWGN). The analytical BER performance of the self-normalizing receiver, validated by the simulation results, is shown to be significantly better than that of the soft-decision linear-combining receiver under the conditions of the worst-case MTJ and AWGN.
