Tackling problems from the least complicated to the most, Resource Allocation in Uplink OFDMA Wireless Systems provides readers with a comprehensive look at resource allocation and scheduling techniques (for both single and multi-cell deployments) in uplink OFDMA wireless networks--relying on convex optimization and game theory to thoroughly analyze performance. Inside, readers will find topics and discussions on:Formulating and solving the uplink ergodic sum-rate maximization problemProposing suboptimal algorithms that achieve a close performance to the optimal case at a considerably reduced co.
