多用户通信的基于Copula的界--第一部分:平均性能

Copula-Based Bounds for Multi-User Communications -- Part I: Average Performance

Eduard A. Jorswieck, Karl-Ludwig Besser

摘要:

统计独立或正相关的衰落模型通常用于计算无线通信的平均性能。然而,存在具有负依赖性的场景,因此感兴趣的是不同的性能度量如何针对通道的不同的一般依赖性结构而表现。特别是最佳情况和最坏情况的界限是实际相关的系统设计准则。在这封由两部分组成的信中,我们提出了依赖建模的方法和工具,这些方法和工具可以应用于分析和设计利用和创建有效衰落信道的依赖关系的多用户通信系统。第一部分着重于快衰落与平均性能指标,而第二部分考虑慢衰落与中断性能指标。

英文摘要:

Statistically independent or positively correlated fading models are usually applied to compute the average performance of wireless communications. However, there exist scenarios with negative dependency and it is therefore of interest how different performance metrics behave for different general dependency structures of the channels. Especially best-case and worst-case bounds are practically relevant as a system design guideline. In this two-part letter, we present methods and tools from dependency modeling which can be applied to analyze and design multi-user communications systems exploiting and creating dependencies of the effective fading channels. The first part focuses on fast fading with average performance metrics, while the second part considers slow fading with outage performance metrics.
