论文摘要
在本文中，我们使用Quadriga中的理论计算和数值模拟研究了多输入 - 多数输出（MIMO）系统中接收器和发射器的干扰取消能力。我们研究了所谓的零通道零孔（RCZF）的预编码类别以及最小MSE干扰排斥组合器（MMSE-IRC）和QR最大似然检测（QR-MLD）接收器。基于非常简单但非常有用的代数操纵，它们的渐近等效性是在分析中证明的，并通过模拟证明。我们的理论和实验结果证实，MMSE-IRC和QR-MLD接收器与RCZF预编码结合使用，可偶然地提供完全干扰抑制。
In this paper, we study the interference cancellation capabilities of receivers and transmitters in multiple-input-multiple-output (MIMO) systems using theoretical calculations and numerical simulations in Quadriga. We study so-called Reduced Channel Zero-Forcing (RCZF) class of precoding as well as Minimum MSE Interference Rejection Combiner (MMSE-IRC) and QR Maximum Likelihood Detection (QR-MLD) receivers. Based on very simple but extremely useful algebraic manipulations, their asymptotical equivalence is proven analytically and demonstrated via simulations. Our theoretical and experimental results confirm that MMSE-IRC and QR-MLD receivers in combination with the RCZF precoding provide complete interference suppression asymptotically.
