研究了服务质量(Qos)驱动的SC-FDMA上行链路的节能设计。资源分配问题被描述为统计服务质量保证下基于有效容量的每焦耳比特容量的最大化问题，由于SC-FDMA的特定约束而变得复杂。我们用典型对偶理论来解决这个问题。数值结果表明，所提出的节能设计在满足不同用户的服务质量要求的同时，显著提高了系统的能量效率。
We investigate Quality-of-Service (QoS) driven energy efficient design of SC-FDMA uplink. The resource allocation problem is formulated as a maximization of effective capacity based bits-per-joule capacity under statistical QoS provisioning, which is complicated due to specific constraints of SC-FDMA. We solve the problem using Canonical duality theory. Numerical results show that the proposed energy efficient design significantly enhances the energy efficiency while satisfying the QoS requirements of different users.
