6G Wireless Systems: Vision, Requirements, Challenges, Insights, and Opportunities
Harsh Tataria, Mansoor Shafi, Andreas F. Molisch +3
Mobile communications have been undergoing a generational change every ten years or so. However, the time difference between the so-called "G's" is also decreasing. While fifth-gen…
Favorable Propagation with User Cluster Sharing
Chelsea Miller, Peter J. Smith, Pawel A. Dmochowski +2
We examine the favorable propagation (FP) behavior of a massive multi-user multiple-input-multiple-output (MU-MIMO) system equipped with a uniform linear array (ULA), horizontal un…
Standardization of Propagation Models: 800 MHz to 100 GHz -- A Historical Perspective
Harsh Tataria, Katsuyuki Haneda, Andreas F. Molisch +2
Propagation models constitute a fundamental building block of wireless communications research. Before we build and operate real systems, we must understand the science of radio pr…
A Light Signalling Approach to Node Grouping for Massive MIMO IoT Networks
Emma Fitzgerald, Michał Pióro, Harsh Tataria +3
Massive MIMO is a leading technology to connect very large numbers of energy constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge r…
Real-Time Implementation Aspects of Large Intelligent Surfaces
Harsh Tataria, Fredrik Tufvesson, Ove Edfors
With the potential to provide a clean break from massive multiple-input multiple-output, large intelligent surfaces (LISs) have recently received a thrust of research interest. Var…
Impact of Spatially Consistent Channels on Digital Beamforming for Millimeter-Wave Systems
Harsh Tataria, Fredrik Tufvesson
The premise of massive multiple-input multiple-output (MIMO) is based around coherent transmission and detection. Majority of the vast literature on massive MIMO presents performan…
Massive MIMO Asymptotics for Ray-Based Propagation Channels
Shuang Li, Peter Smith, Pawel Dmochowski +3
Favorable propagation (FP) and channel hardening (CH) are desired properties in massive multiple-input multiple-output (MIMO) systems. To date, these properties have primarily been…
Amplitude and Phase Estimation for Absolute Calibration of Massive MIMO Front-Ends
Guoda Tian, Harsh Tataria, Fredrik Tufvesson
Massive multiple-input multiple-output (MIMO) promises significantly higher performance relative to conventional multiuser systems. However, the promised gains of massive MIMO syst…
Real-Time Deployment Aspects of C-Band and Millimeter-Wave 5G-NR Systems
Mansoor Shafi, Harsh Tataria, Andreas F. Molisch +2
Fifth-generation (5G) new radio (NR) deployments are being rolled out in both the C-band (3.3 - 5.0 GHz) and millimeter-wave (mmWave) band (24.5 - 29.5 GHz). For outdoor scenarios,…
