Abstract

In this paper, we deal with the estimation of the ergodic capacity of large MIMO systems, using training sequences whose lengths are of the same order of magnitude than the number of antennas. In this context, the traditional estimator becomes inconsistent. Following the ideas developed by Girko in the context of the so-called theory of G-estimation, we propose a new estimator. We analyze its asymptotic behaviour and show, using numerical simulations, that it tends to improve significantly the performance of the standard estimate for a realistic number of antennas.
MIMO信道遍历容量的g估计
本文利用与天线数目相同数量级的训练序列,研究了大型MIMO系统遍历容量的估计问题。在这种情况下,传统的估计变得不一致。根据Girko在所谓的g估计理论的背景下提出的思想,我们提出了一个新的估计量。我们分析了它的渐近行为,并使用数值模拟表明,它倾向于显著提高对实际天线数量的标准估计的性能。
