Sequential In-Network Processing for Cell-Free Massive MIMO with Capacity-Constrained Parallel Radio Stripes
Sangwon Jo, Hoon Lee, Seok-Hwan Park
To ensure coherent signal processing across distributed Access Points (APs) in Cell-Free Massive Multiple-Input Multiple-Output (CF-mMIMO) systems, a fronthaul connection between t…
Generalized Reduced-WMMSE Approach for Cell-Free Massive MIMO With Per-AP Power Constraints
Wonsik Yoo, Daesung Yu, Hoon Lee +1
The optimization of cooperative beamforming vectors in cell-free massive MIMO (mMIMO) systems is presented where multi-antenna access points (APs) support downlink data transmissio…
Joint Precoding and Fronthaul Compression for Cell-Free MIMO Downlink With Radio Stripes
Sangwon Jo, Hoon Lee, Seok-Hwan Park
A sequential fronthaul network, referred to as radio stripes, is a promising fronthaul topology of cell-free MIMO systems. In this setup, a single cable suffices to connect access…
Learning Decentralized Power Control in Cell-Free Massive MIMO Networks
Daesung Yu, Hoon Lee, Seung-Eun Hong +1
This paper studies learning-based decentralized power control methods for cell-free massive multiple-input multiple-output (MIMO) systems where a central processor (CP) controls ac…
A Bipartite Graph Neural Network Approach for Scalable Beamforming Optimization
Junbeom Kim, Hoon Lee, Seung-Eun Hong +1
Deep learning (DL) techniques have been intensively studied for the optimization of multi-user multiple-input single-output (MU-MISO) downlink systems owing to the capability of ha…
