论文摘要
通常应用统计独立或正相关的褪色模型来计算无线通信的平均性能。但是，存在具有负依赖性的方案，因此感兴趣的是不同的性能指标如何对渠道的不同通用依赖性结构进行行为。尤其是最佳案例和最差案例界限实际上是系统设计指南。在这两个部分的字母中，我们提出了依赖性建模的方法和工具，可以应用于分析和设计多用户通信系统利用并创建有效褪色渠道的依赖性。第一部分的重点是通过平均性能指标快速褪色，而第二部分则考虑使用中断性能指标逐渐消失。
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.
