N2 - 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) or noncoherent iterative interference cancellation assisted multiuser detector (IIC-MUD) is employed, in order to implement low-complexity detection. The bit error rate (BER) and throughput performance of the FFH/MFSK DMA systems are investigated, when assuming communications over Nakagami-m fading channels. Our studies show that the FFH/MFSK DMA is a high-flexibility scheme for application in CRs. It is capable of attaining a substantial throughput without degrading the quality-of-service (QoS) of primary radios (PRs).
