论文摘要
这是针对具有非线性接收器的多用户MIMO（MU-MIMO）系统的链接适应（LA）和物理层（PHY）抽象的第二部分的第二部分。第一部分提出了一个新的度量标准，称为检测器，称为比率解码率（BMDR），是非线性接收器的等效性信号与交换后噪声比率（SINR）。由于该BMDR没有封闭形式的表达式，因此可以有效地提出基于机器学习的方法来估计它。在这一部分中，第一部分中开发的概念用于开发LA的新算法，可用检测器列表中的动态检测器选择以及具有任意接收器的MU-MIMO系统中的PHY抽象。提出了证实所提出算法功效的广泛仿真结果。
This is the second part of a two-part paper that focuses on link-adaptation (LA) and physical layer (PHY) abstraction for multi-user MIMO (MU-MIMO) systems with non-linear receivers. The first part proposes a new metric, called bit-metric decoding rate (BMDR) for a detector, as being the equivalent of post-equalization signal-to-interference-noise ratio (SINR) for non-linear receivers. Since this BMDR does not have a closed form expression, a machine-learning based approach to estimate it effectively is presented. In this part, the concepts developed in the first part are utilized to develop novel algorithms for LA, dynamic detector selection from a list of available detectors, and PHY abstraction in MU-MIMO systems with arbitrary receivers. Extensive simulation results that substantiate the efficacy of the proposed algorithms are presented.
