Robust MMSE Precoding for Out-of-Cluster Interference Mitigation in Cell-Free MIMO Networks
André R. Flores, Rodrigo C. de Lamare
In this work, we develop a linear robust minimum mean-square error (RMMSE) precoder to mitigate the effects of imperfect channel state information (CSI) and the intra-cluster (ICL)…
Study of Robust Power Allocation for User-Centric Cell-Free Massive MIMO Networks
Saeed Mashdour, Saeed Mohammadzadeh, André R. Flores +3
In cell-free massive multiple-input multiple-output (MIMO) networks, robust resource allocation is critical to ensure reliable system performance in the presence of channel uncerta…
Robust Precoding for Resilient Cell-Free Networks
Saeed Mashdour, André R. Flores, Rodrigo C. de Lamare
This paper presents a robust precoder design for resilient cell-free massive MIMO (CF-mMIMO) systems that minimizes the weighted sum of desired signal mean square error (MSE) and r…
Study of Robust Resource Allocation in Cell-Free Multiple-Antenna Networks
S. Mashdour, A. Flores, R. C. de Lamare
Cell-free networks outperform cellular networks in many aspects, yet their efficiency is affected by imperfect channel state information (CSI). In order to address this issue, this…
Robust Precoding for Rate-Splitting-Based Cell-Free MU-MIMO Networks
A. Flores, R. de Lamare
Cell-free (CF) multiuser multiple-input multiple-output (MU-MIMO) systems are an emerging technology that provides service simultaneously to multiple users but suffers from multius…
Study of Robust Multiuser Scheduling and Power Allocation in Cell-Free MIMO Networks
S. Mashdour, A. R. Flores, S. Salehi +2
This paper introduces a robust resource allocation framework for the downlink of cell-free massive multi-input multi-output (CF-mMIMO) networks to address the effects caused by imp…
