- Abstract
- In this paper, we provide an exact capacity derivation for the ergodic capacity of the secondary user in a spectrum sharing environment. Considering the effect of the interference from the primary user, the closed-form expression for the ergodic capacity is obtained under both average and peak received-power constraints at the primary user. Numerical results show that our derived ergodic capacity perfectly matches the results from a computer simulation.
