On the Use of FFH-MFSK for Ultra-Low Power Communications in a Jamming Environment

We are interested in a communication system that operates the presence of an intelligent jammer, under stringent power constraints, but with flexible bandwidth constraints.We optimize some key elements transceiver design for low consumption, and thus high complexity components system, such as matched filters (MF), forward error correction (FEC) employs iterative decoders, coherent demodulators, bandwidth-efficient modulation formats, not feasible this research. Rather, our is designed using M -ary frequency shift keying (MFSK) non-coherent detection fast hopping (FFH), optimized two-pole bandpass (BPF), Reed-Solomon (RS) codes hard-decision decoding. Among other things, we show by properly optimizing parameters BPFs RS codes, can to be significantly less complex than MF performance loss 1.4 dB most scenarios considered. Further, 2-pole BPF actually outperform corresponding up 2.4 multi-tone jamming.
