Abstract :
Following a model similar to that of Telatar and Gallager, multiuser communication systems with a varying number of users are studied. It is shown that fading causes variability in the service process, and reduces the effective service rate seen by a user. This result is used to design a power control scheme that balances the twin goals of low service variability and high mean service rate.
