Abstract: In this paper, we derive analytical expressions for
outage probability and ergodic capacity of a spectrum sharing
system with multiuser diversity under Nakagami-m fading. In
particular, multiuser diversity effects in such systems where
several secondary users utilize the licensed spectrum of the
primary user are considered. The best and worst channel quality
scenarios are investigated for transmission from a number of
secondary transmitters. Numerical analysis and simulations are
shown to reveal the effects of multiusers and fading parameters
on the considered system.
