LoFi User Scheduling for Multiuser MIMO Wireless Systems
Alexandra Gallyas-Sanhueza, Gian Marti, Victoria Palhares +2
We propose new low-fidelity (LoFi) user equipment (UE) scheduling algorithms for multiuser multiple-input multiple-output (MIMO) wireless communication systems. The proposed method…
Low-Complexity Blind Parameter Estimation in Wireless Systems with Noisy Sparse Signals
Alexandra Gallyas-Sanhueza, Christoph Studer
Baseband processing algorithms often require knowledge of the noise power, signal power, or signal-to-noise ratio (SNR). In practice, these parameters are typically unknown and mus…
Hardware-Aware Beamspace Precoding for All-Digital mmWave Massive MU-MIMO
Emre Gönültaş, Sueda Taner, Alexandra Gallyas-Sanhueza +2
Massive multi-user multiple-input multiple-output (MU-MIMO) wireless systems operating at millimeter-wave (mmWave) frequencies enable simultaneous wideband data transmission to a l…
Blind SNR Estimation and Nonparametric Channel Denoising in Multi-Antenna mmWave Systems
Alexandra Gallyas-Sanhueza, Christoph Studer
We propose blind estimators for the average noise power, receive signal power, signal-to-noise ratio (SNR), and mean-square error (MSE), suitable for multi-antenna millimeter wave…
Sparsity-Adaptive Beamspace Channel Estimation for 1-Bit mmWave Massive MIMO Systems
Alexandra Gallyas-Sanhueza, Seyed Hadi Mirfarshbafan, Ramina Ghods +1
We propose sparsity-adaptive beamspace channel estimation algorithms that improve accuracy for 1-bit data converters in all-digital millimeter-wave (mmWave) massive multiple-input…
Beamspace Channel Estimation for Massive MIMO mmWave Systems: Algorithm and VLSI Design
Seyed Hadi Mirfarshbafan, Alexandra Gallyas-Sanhueza, Ramina Ghods +1
Millimeter-wave (mmWave) communication in combination with massive multiuser multiple-input multiple-output (MU-MIMO) enables high-bandwidth data transmission to multiple users in…
