Activity Detection in Distributed MIMO: Distributed AMP via Likelihood Ratio Fusion
Jianan Bai, Erik G. Larsson
We develop a new algorithm for activity detection for grant-free multiple access in distributed multiple-input multiple-output (MIMO). The algorithm is a distributed version of the…

Local Partial Zero-Forcing Combining for Cell-Free Massive MIMO Systems
Jiayi Zhang, Jing Zhang, Emil Björnson +1
Cell-free massive multiple-input multiple-output (MIMO) provides more uniform spectral efficiency (SE) for users (UEs) than cellular technology. The main challenge to achieve the b…
