项目摘要
In wireless communication systems, users with heterogeneous information content such as data, voice, and multimedia constrain the network by having different reliability requirements. In this project a framework which can provide heterogeneous reliability guarantees for the users is considered.This adds a completely new dimension to the trade-off of performance in a wireless network, and is unique to multiterminal communication systems. It is as if the network has some amount of reliability that can be allocated among the users. This is a very general concept and can be applied in any multiterminalcommunication problem.This is accomplished by defining individual probabilities of errors for the users in the network. Hence for a fixed vector of rates of the users, a system can provide a trade-off of reliabilities among the users. This set of achievable reliabilities is referred to as the multiuser reliability profile of a multiuser network. This profile is a function of the vector of transmission rates inside the capacity region.For a wireless system employing multiple antennas, this profile is referred to as multiuser diversity gainprofile. Further, these guarantees are directly manifested in the physical layer and can be translated into QoS guarantees in the higher layers in the network architecture. This is a marked shift from conventional approaches that relegate this task to the higher network layers. Hence in a heterogeneous wireless networks,heterogeneous QoS guarantees can be more efficiently realized using the techniques considered in this project. This project is expected to have a significant impact on the design of the next generation of wireless networks.
在 在无线通信系统中,具有诸如数据、语音和多媒体的异构信息内容的用户通过具有不同的可靠性要求来约束网络。在这个项目中,一个框架,它可以提供异构的可靠性保证的用户被认为是。这增加了一个全新的层面,在无线网络中的性能权衡,是唯一的多终端通信系统。这就好像网络有一定的可靠性,可以在用户之间分配。这是一个非常普遍的概念,可以应用于任何多终端通信问题,这是通过定义网络中用户的个人错误概率来实现的。因此,对于用户的速率的固定向量,系统可以在用户之间提供可靠性的折衷。这组可实现的可靠性被称为多用户网络的多用户可靠性简档。该分布是容量区域内传输速率矢量的函数,对于采用多天线的无线系统,该分布被称为多用户分集增益分布。此外,这些保证直接在物理层中表现出来,并且可以在网络架构中的更高层中转换为QoS保证。这是传统方法的一个显著转变,传统方法将此任务移交给更高的网络层。因此,在异构无线网络中,异构QoS保证可以更有效地实现使用本项目中考虑的技术。预计该项目将对下一代无线网络的设计产生重大影响。
