Low-Complexity Tensor Beamforming for RIS-Aided Multiuser Multistream MIMO Systems
Bruno Sokal, André L. F. de Almeida, Martin Haardt
We address joint active and passive beamforming for uplink RIS-assisted multi-user multi-stream MIMO systems with joint detection. The coupled design of the receive combiner, block…
Max-Min Beamforming for Large-Scale Cell-Free Massive MIMO: A Randomized ADMM Algorithm
Bin Wang, Jun Fang, Yue Xiao +1
We consider the problem of max-min beamforming (MMB) for cell-free massive multi-input multi-output (MIMO) systems, where the objective is to maximize the minimum achievable rate a…
Probabilistic Position-Aided Beam Selection for mmWave MIMO Systems
Joseph K. Chege, Arie Yeredor, Martin Haardt
Millimeter-wave (mmWave) MIMO systems rely on highly directional beamforming to overcome severe path loss and ensure robust communication links. However, selecting the optimal beam…
Enhanced channel estimation for double RIS-aided MIMO systems using coupled tensor decomposition
Gerald C. Nwalozie, Andre L. F. de Almeida, Martin Haardt
In this paper, we consider a double-RIS (D-RIS)-aided flat-fading MIMO system and propose an interference-free channel training and estimation protocol, where the two single-reflec…
Direction of Arrival Estimation with Sparse Subarrays
W. Leite, R. C. de Lamare, Y. Zakharov +2
This paper proposes design techniques for partially-calibrated sparse linear subarrays and algorithms to perform direction-of-arrival (DOA) estimation. First, we introduce array ar…
