Decentralized MIMO Systems with LMMSE Receivers and Imperfect CSI

Autor: Zhuang, Zeyan, Zhang, Xin, Xu, Dongfang, Song, Shenghui, Eldar, Yonina C.

Centralized baseband processing (CBP) is required to achieve the full potential of massive multiple-input multiple-output (MIMO) systems. However, due to the large number of antennas, CBP suffers from two major issues: 1) Tremendous data interconnect

Fundamental Limits of Two-Hop MIMO Channels: An Asymptotic Approach

Autor: Zhuang, Zeyan, Zhang, Xin, Xu, Dongfang, Song, Shenghui

Multi-antenna relays and intelligent reflecting surfaces (IRSs) have been utilized to construct favorable channels to improve the performance of wireless systems. A common feature between relay systems and IRS-aided systems is the two-hop multiple-in

Active IRS-Aided MIMO Systems: How Much Gain Can We Get?

Autor: Zhuang, Zeyan, Zhang, Xin, Xu, Dongfang, Song, Shenghui

Intelligent reflecting surfaces (IRSs) have emerged as a promising technology to improve the efficiency of wireless communication systems. However, passive IRSs suffer from the ``multiplicative fading" effect, because the transmit signal will go thro
