Efficient Design of Fronthaul-Constrained Uplink Reception for Cell-Free XL-MIMO
Dogon Kim, Hyunmin Noh, Seok-Hwan Park
With the evolution of multiple-input multiple-output (MIMO) technology toward extremely large (XL) MIMO systems comprising hundreds of, or more, antennas, this work investigates sc…
Multi-Satellite Cooperative MIMO Transmission: Statistical CSI-Aware RSMA Precoding Design
Sangwon Jo, Seok-Hwan Park
We investigate inter-satellite cooperative transmission in a multiple low-Earth orbit (LEO) satellite communication system to enhance spectral efficiency. Specifically, we design m…
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…
