Hybrid centralized-distributed precoding in fronthaul-constrained CF-mMIMO systems
Zahra Mobini, Hien Quoc Ngo, Ardavan Rahimian +4
We investigate a fronthaul-limited cell-free massive multiple-input multiple-output (CF-mMIMO) system and propose a hybrid centralized-distributed precoding strategy that dynamical…
Steady-State Spread Bounds for Graph Diffusion via Laplacian Regularisation in Networked Systems
Ardavan Rahimian
We study how far a diffusion process on a graph can deviate from a designed starting pattern when the pattern is generated via Laplacian regularisation. Under standard stability co…
