Leakage-Based Precoder Optimization and Deep Unfolding for User-Centric Cell-Free Massive MIMO

This article investigates the leakage-based precoder design for user-centric cell-free massive MIMO systems. Given the clustered APs for each UE, the problem is formulated as a group sparse optimization to maximize the leakage rate under per-AP power constraints. Its equivalent formulation is derive...
