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…
Space MIMO: Direct Unmodified Handheld to Multi-Satellite Communication
Yasaman Omid, Zohre Mashayekh Bakhsh, Farbod Kayhan +2
This paper examines the uplink transmission of a single-antenna handsheld user to a cluster of satellites, with a focus on utilizing the inter-satellite links to enable cooperative…
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…
A Design of Low-Projection SCMA Codebooks for Ultra-Low Decoding Complexity in Downlink IoT Networks
Qu Luo, Zilong Liu, Gaojie Chen +3
This paper conceives a novel sparse code multiple access (SCMA) codebook design which is motivated by the strong need for providing ultra-low decoding complexity and good error per…
