The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Power control can be used to reduce the co-channel interference, near-far effect. This leads to improved channel capacity and longer battery life. In this paper, we consider distributed power control algorithms, which are based on local information within a cell. We adopt the method of Projection Onto Convex Sets- (POCS) as an iterative approach to obtain the minimum protection ratio. Numerical result shows that the POCS- method achieves much faster convergence and improved outage probability than other conventional methods.
