ISTA-Based Joint Dictionary Learning and Channel Estimation for XL-MIMO Systems
Arttu Arjas, Italo Atzeni
Channel estimation in extra-large multiple-input multiple-output systems is challenging due to near-field propagation, where the array response depends on both the angle and distan…
Cross-Predictive Sparse Bayesian Learning with Application to XL-MIMO Channel Estimation
Arttu Arjas, Italo Atzeni
Accurate channel estimation is a key requirement in extremely large-scale multiple-input multiple-output (XL-MIMO) systems. Sparse Bayesian learning (SBL) is a well-established fra…
Nonlinear Sparse Bayesian Learning Methods with Application to Massive MIMO Channel Estimation with Hardware Impairments
Arttu Arjas, Italo Atzeni
Accurate channel estimation is critical for realizing the performance gains of massive multiple-input multiple-output (MIMO) systems. Traditional approaches to channel estimation t…
Enhanced Sparse Bayesian Learning Methods with Application to Massive MIMO Channel Estimation
Arttu Arjas, Italo Atzeni
We consider the problem of sparse channel estimation in massive multiple-input multiple-output systems. In this context, we propose an enhanced version of the sparse Bayesian learn…
