Using these metrics, we then study and analyze the impact of using guard bands on the performance of cognitive radio networks. We show that taking guard bands ...

In this work, we model a multichannel access cognitive radio as a continuous time Markov process under the realistic assumption of non-ideal filters (i.e., ...

This work model cognitive radio network as a continuous-time Markov process and derives blocking probability, forced termination probability, spectrum ...

In cognitive radio networks, secondary spectrum users detect available frequency channels by spectrum sensing. In general, the sensing time is communication ...

Abstract—Spectrum access/sharing algorithms for Dynamic spectrum access (DSA) networks are often designed without accounting for adjacent-channel ...

This work proposes a novel guard-band-aware channel assignment scheme for DSA systems that reduces the number of required guard channels for a given ...
