Near and Far Field Model Mismatch: Implications on 6G Communications, Localization, and Sensing
Ahmed Elzanaty, Jiuyu Liu, Anna Guerra +3
The upcoming 6G technology is expected to operate in near-field (NF) radiating conditions thanks to high-frequency and electrically large antenna arrays. Although several studies h…
A Spatially Non-stationary Fading Channel Model for Simulation and (Semi-) Analytical Study of ELAA-MIMO
Jiuyu Liu, Yi Ma, Rahim Tafazolli
In this paper, a novel spatially non-stationary fading channel model is proposed for multiple-input multiple-output (MIMO) system with extremely-large aperture service-array (ELAA)…
Alternative Normalized-Preconditioning for Scalable Iterative Large-MIMO Detection
Jiuyu Liu, Yi Ma, Rahim Tafazolli
Signal detection in large multiple-input multiple-output (large-MIMO) systems presents greater challenges compared to conventional massive-MIMO for two primary reasons. First, larg…
Leveraging User-Wise SVD for Accelerated Convergence in Iterative ELAA-MIMO Detections
Jiuyu Liu, Yi Ma, Rahim Tafazolli
Numerous low-complexity iterative algorithms have been proposed to offer the performance of linear multiple-input multiple-output (MIMO) detectors bypassing the channel matrix inve…
Achieving Maximum-likelihood Detection Performance with Square-order Complexity in Large Quasi-Symmetric MIMO Systems
Jiuyu Liu, Yi Ma, Rahim Tafazolli
We focus on the signal detection for large quasi-symmetric (LQS) multiple-input multiple-output (MIMO) systems, where the numbers of both service (M) and user (N) antennas are larg…
