Abstract

In this work we present a unified treatment on the most common metrics used in the utility function of state-of-the-art user selection algorithms for sum rate maximization in MISO systems under Zero-Forcing Beamforming. We present the way that such metrics are used to maximize the total sum rate and the relations held among each other. Via simulation we found upper bounds of the average total sum rate for each metric which allow us to establish a benchmark in terms of sum rate performance and a trade-off between the metric accuracy needed to maximize the sum rate and the computational complexity required to determine each metric.
具有零强迫波束形成的多用户miso系统中速率最大化的度量
在这项工作中,我们对零强迫波束形成下MISO系统中用于求和速率最大化的最先进用户选择算法的效用函数中使用的最常见度量进行了统一处理。我们提出的方式,这些指标是用来最大化的总和率和彼此之间的关系。通过模拟,我们发现了每个指标的平均总和率的上限,这使我们能够根据和率性能建立基准,并在最大化和率所需的度量精度和确定每个指标所需的计算复杂性之间进行权衡。
