Abstract :
In this paper, the problem of maximizing the number of users that can be served in a wireless network under QoS requirements and transmitter power limitations is studied. This problem is mathematically defined and then transformed into a novel form which is solvable by geometric programming. A suboptimum solution is proposed and the performance of this method is investigated by simulations.
