Год издания: 0000
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.

As part of the dynamics of international economic cooperation by the need for mutual settlement operations, so the problem of organization of settlements is an important place for the economically active subjects, especially in a globalized economic space in the functioning of transnational structures and scale of the export, import and international financial transactions. In agreeing on the order of calculations, the participants determined the form of payment in order to fulfill the financial obligations of the agreement – regulated by means of voluntary compliance through a credit institution liabilities, characterized by specific features on the order of transfer of funds to the account, a certain kind of settlement document, as well as office procedures. The source of payment relations is the need to have one contractor expressed in the appropriate disposition, the other in shortage. This relationship gives rise as a consequence of the relationship with the lending institution. Need to accession will intensify in the subjects of international payment relationship.
