Resource Allocation in Uplink OFDMA Wireless Systems: Optimal Solutions and Practical Implementations

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 problem

• Proposing suboptimal algorithms that achieve a close performance to the optimal case at a considerably reduced complexity and lead to fairness when the appropriate utility is used

• Investigating the performance and extensions of the proposed suboptimal algorithms in a distributed base station scenario

• Studying distributed resource allocation where users take part in the scheduling process, and considering scenarios with and without user collaboration

• Formulating the sum-rate maximization problem in a multi-cell scenario, and proposing efficient centralized and distributed algorithms for intercell interference mitigation

• Discussing the applicability of the proposed techniques to state-of-the-art wireless technologies, LTE and WiMAX, and proposing relevant extensions

Along with schematics and figures featuring simulation results, Resource Allocation in Uplink OFDMA Wireless Systems is a valuable book for?wireless communications and cellular systems professionals and students.
