The focus of this paper is on the modeling and performance analysis of an unreliable opportunistic spectrum sharing (OSS) system at the call level with sensitive secondary users. Unreliable spectrum sensing is modeled by type I and type II false alarm events and class-A and class-B misdetection events, which brings more flexibility for the purpose of performance evaluation. Spectrum sensing errors negatively impact the performance of primary users and secondary users, particularly when a call collision happens. To maximize the protection of primary users under call collisions, it is required in the system design that secondary users be sensitive to the call collisions, to protect primary users. We model the unreliable OSS system through a two-dimensional Markov process and develop the steady-state probabilities of the system as well as several performance metrics of interest.
