Abstract EN
Fast frequency hopping (FFH) is commonly used as an antijamming communication method.
In this paper, we propose efficient adaptive jamming suppression schemes for binary phase shift keying (BPSK) based coherent FFH system, namely, weighted equal gain combining (W-EGC) with the optimum and suboptimum weighting coefficient.
We analyze the bit error ratio (BER) of EGC and W-EGC receivers with partial band noise jamming (PBNJ), frequency selective Rayleigh fading, and channel estimation errors.
Particularly, closed-form BER expressions are presented with diversity order two.
Our analysis is verified by simulations.
It is shown that W-EGC receivers significantly outperform EGC.
As compared to the maximum likelihood (ML) receiver in conventional noncoherent frequency shift keying (FSK) based FFH, coherent FFH/BPSK W-EGC receivers also show significant advantages in terms of BER.
Moreover, W-EGC receivers greatly reduce the hostile jammers’ jamming efficiency.
