Information exchange among a group of users is implemented with the aid of fast frequency-hopping M-ary frequency-shift keying multi-way relay (FFH/MFSK MWR). The FFH/MFSK MWR scheme uses two time-slots per symbol for achieving the information exchange, regardless of the number of users involved. During the first time-slot, all the users communicate with a relay based on the FFH/MFSK principles. Then,...
In this paper, a novel WSN framework, namely the FH/MFSK WSN, is proposed, which monitors M-ary events and conveys signals from local sensors to fusion center with the aid of frequency-hopping (FH) and M-ary frequency-shift keying (MFSK) techniques. The source events under observation by local sensors are assumed to have M states. The estimates of local sensors are transmitted to the fusion center...
In this paper, the achievable performance of Reed-Solomon (RS)-coded slow-frequency-hopping assisted M-ary frequency-shift keying using various erasure-insertion (EI) schemes is investigated when communicating over uncorrelated Rayleigh fading channels in the presence of multitone jamming. Three different EI schemes are considered, which are based on the output threshold test, on the ratio threshold...
