CAREER: A Framework for Resource Allocation in Wireless Networks with Multi-User Receivers

摘要NCR-9734090 Tse，大卫机构：加州-伯克利大学标题：职业生涯：多用户接收器无线网络中的资源分配框架_ 无线网络设计中的一个核心问题是如何最大限度地利用有限的资源来满足应用的服务质量要求。两种特定类别的技术受到了广泛关注：1）在物理层，开发减轻用户之间的干扰的新颖的多用户接收机结构; 2）在网络层，适应信道条件的资源（诸如发射功率、带宽和比特率）的动态分配。虽然对于常规多址技术的联网方面是很好理解的，但是对于这些多用户接收机的上下文中的资源分配和功率控制的问题不能这样说。 在这个项目中，我们建议建立一个连贯的框架来研究多用户接收机的动态资源分配问题，在一个综合的方式，借鉴信息论作为性能评估的基本依据。 我们将在拟议框架中研究的具体主题是：1）线性多用户接收机：最佳功率控制下的系统容量; 2）香农容量实现多用户接收机的最佳资源分配; 3）使用自适应天线阵列的容量增益; 4）多径衰落对可实现容量的影响; 5）具有多用户接收机的蜂窝网络的资源分配。 无线网络中资源分配和QOS供应问题的解决方案需要网络和物理层概念的结合。考虑到这一点，我的教育计划旨在实现更一般的目标，为我们的学生提供一个坚实的理论基础，在网络和通信，以及更具体的目标，突出网络和物理层概念之间的相互作用，在无线网络。 这些目标将通过四个学科的课程开发来实现。

ABSTRACT NCR-9734090 Tse, David Institution: University of California - Berkeley Title: CAREER: A Framework for Resource Allocation in Wireless Networks with Multi-User Receivers ________________________________________________________________ A central problem in the design of wireless networks is how to use the limited resources most to meet the quality-of-service requirements of applications. Two particular classes of techniques have received much attention: 1) at the physical layer, development of novel multi-user receiver structures which mitigate interference between users; 2) at the network layer, dynamic allocation of resources such as transmit power, bandwidth and bit-rates in adaptation to channel conditions. While the networking aspects for conventional multi-access techniques are well understood, the same cannot be said for problems of resource allocation and power control in the context of these multi-user receivers. In this project, we propose to establish a coherent framework to study problems of dynamic resource allocation for multi-user receivers in an integrated manner, drawing on information theory as a fundamental basis for performance evaluation. The specific topics we will study in the proposed framework are: 1) linear multi-user receivers: system capacity under optimal power control; 2) optimal resource allocation for Shannon capacity-achieving multi-user receivers; 3) capacity gain from the use of adaptive antenna arrays; 4) impact of multipath fading on achievable capacity; 5) resource allocation for cellular networks with multi-user receivers. The solution of problems in resource allocation and QOS provisioning in wireless networks requires a marriage of networking and physical layer concepts. With this in mind, my education plan aims to accomplish the more general goal of providing a solid theoretical basis to our students in networking and communications, as well as the more specific goal of highlighting the interplay between networking and physica l layer concepts in wireless networking. These goals will be implemented by course development in four subjects.
