【 摘 要 】

In this thesis, we investigate sensing-based spectrum sharing in a cognitive radio network with multiple primary destinations and multiple secondary destinations. A secondary destination with the best channel gain is selected to improve reliability of the secondary network. We derive the exact outage probability of the secondary network in closed-form in the presence of interference from the primary source. Also, we derive an upper-bound of the outage probability of the primary network in closed-form. The validity of the analysis is verified by computer simulations.
