This paper proposes a fast frequency-hopping M-ary frequency-shift keying dynamic multiple-access (FFH/MFSK DMA) scheme for application in cognitive radios (CRs). For characterising the performance of the FFH/MFSK DMA systems, primary users (PUs) are assumed to become active according to a Poisson process. In our FFH/MFSK DMA system, the noncoherent majority vote assisted single-user detector (MV-SUD)...
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...
