Intelligent Reflecting Surfaces at Terahertz Bands: Channel Modeling and Analysis
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +2
An intelligent reflecting surface (IRS) at terahertz (THz) bands is expected to have a massive number of reflecting elements to compensate for the severe propagation losses. Howeve…
Intelligent Reflecting Surfaces with Spatial Modulation: An Electromagnetic Perspective
Okan Yurduseven, Stylianos D. Assimonis, Michail Matthaiou
Electromagnetic wave control using the concept of a reflecting surface is first studied as a near-field and a far-field problem. Using a secondary source present in a wireless comm…
The Road to 6G: Ten Physical Layer Challenges for Communications Engineers
Michail Matthaiou, Okan Yurduseven, Hien Quoc Ngo +3
While the deployment of 5G cellular systems will continue well in to the next decade, much interest is already being generated towards technologies that will underlie its successor…
Massive MIMO with a Generalized Channel Model: Fundamental Aspects
Michail Matthaiou, Hien Quoc Ngo, Peter J. Smith +2
Massive multiple-input multiple-output (MIMO) is becoming a mature technology, and has been approved for standardization in the 5G ecosystem. Although there is a large body of pape…
On the Impact of Spillover Losses in 28 GHz Rotman Lens Arrays for 5G Applications
Muhammad Ali Babar Abbasi, Harsh Tataria, Vincent F. Fusco +1
This work demonstrates the sensitivity of lens antenna arrays operating at millimeter-wave (mmWave) frequencies. Considering a Rotman lens array in receive mode, our investigation…
Does Massive MIMO Fail in Ricean Channels?
Michail Matthaiou, Peter J. Smith, Hien Quoc Ngo +1
Massive multiple-input multiple-output (MIMO) is now making its way to the standardization exercise of future 5G networks. Yet, there are still fundamental questions pertaining to…
