Comments Off on A Novel Spectrum Sensing for Cognitive Radio Networks with Noise Uncertainty
Posted in: IEEE 2017, MATLAB
A Novel Spectrum Sensing for Cognitive Radio Networks with Noise Uncertainty Abstract: This correspondence investigates a joint spectrum sensing scheme in cognitive radio (CR) networks with unknown and dynamic noise variance. A novel Bayesian solution is proposed to recover the dynamic noise variance and detect the occupancy of primary frequency band simultaneously. The states of […]

Comments Off on A Novel Reservation-Based MAC Scheme for Distributed Cognitive Radio Networks
Posted in: IEEE 2017, MATLAB
A Novel Reservation-Based MAC Scheme for Distributed Cognitive Radio Networks Abstract: This paper presents a novel medium access control medium access control (MAC) for distributed single-channel cognitive radio networks (CRNs) denominated cognitive radio reservation MAC (C2RMAC). C2RMAC is intended to be adopted by the nonlicensed users and introduces a double stage scheme to schedule each […]
