N2 - Adjacent channel interference (ACI) is often not considered when spectrum sharing schemes are designed for cognitive radio networks (CRNs). In practice, it is necessary to avoid interference by deploying guard bands between two distinct receptions. However, using guard bands typically reduces spectrum efficiency. In this work, we study the impact of guard bands on spectrum efficiency under different spectrum sharing schemes. Specifically, we model cognitive radio network as a continuous-time Markov process. We derive blocking probability, forced termination probability, spectrum efficiency and average number of guard bands using our Markov model. 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 into consideration is critical as disregarding this realistic issue results in inaccurate conclusions and outcomes.
