卫星通信中非相干大规模MIMO集成

Non-Coherent Massive MIMO Integration in Satellite Communication

Victor Monzon, Vu N. Ha, Jorge Querol, Symeon Chatzinotas

摘要:

大规模多输入多输出(mMIMO)技术已被认为是显著提高诸如5G及更高的后续无线通信系统的传输速率的有效标准。然而,实现该技术一直面临着一个关键问题,获取大量的信道状态信息。首先,由于可计算的高传输延迟,这个问题在集成卫星和地面网络(3GPP-版本15)中变得更加严重。为了解决这个具有挑战性的问题,mMIMO授权的非相干技术可以是一个有前途的解决方案。据我们所知,本文是第一个考虑在卫星通信系统中采用非相干mMIMO的工作。这项工作的目的是分析这一整合所带来的挑战和机遇。此外,我们确定了这方面的问题。在这项工作中提出的初步结果表明,在比特出错率(BER)和天线的数量测量的性能是不远的地面链路所需的。此外,由于mMIMO与非相干方法相结合,我们可以在低信噪比(SNR)状态下工作,这对于卫星链路来说是一个很好的优势。

英文摘要:

Massive Multiple Input-Multiple Output (mMIMO) technique has been considered an efficient standard to improve the transmission rate significantly for the following wireless communication systems, such as 5G and beyond. However, implementing this technology has been facing a critical issue of acquiring much channel state information. Primarily, this problem becomes more criticising in the integrated satellite and terrestrial networks (3GPP-Release 15) due to the countable high transmission delay. To deal with this challenging problem, the mMIMO-empowered non-coherent technique can be a promising solution. To our best knowledge, this paper is the first work considering employing the non-coherent mMIMO in satellite communication systems. This work aims to analyse the challenges and opportunities emerging with this integration. Moreover, we identified the issues in this conjunction. The preliminary results presented in this work show that the performance measured in bit error rate (BER) and the number of antennas are not far from that required for terrestrial links. Furthermore, thanks to mMIMO in conjunction with the non-coherent approach, we can work in a low signal-to-noise ratio (SNR) regime, which is an excellent advantage for satellite links.
