On the Performance Analysis of RIS-Empowered Communications Over Nakagami-m Fading
Dimitris Selimis, Kostas P. Peppas, George C. Alexandropoulos +1
In this paper, we study the performance of wireless communications empowered by Reconfigurable Intelligent Surface (RISs) over Nakagami-m fading channels. We consider two phase con…
On High-Order Capacity Statistics of Spectrum Aggregation Systems over - and - shadowed Fading Channels
Jiayi Zhang, Xiaoyu Chen, Kostas P. Peppas +2
The frequency scarcity imposed by fast growing demand for mobile data service requires promising spectrum aggregation systems. The so-called higher-order statistics (HOS) of the ch…
Asymptotic Error Performance Analysis of Spatial Modulation under Generalized Fading
Kostas P. Peppas, Martin Zamkotsian, Fotis Lazarakis +1
This letter presents a comprehensive framework analyzing the asymptotic error performance of a multiple-input-multiple-output (MIMO) wireless system employing spatial modulation (S…
Dual-hop transmissions with fixed-gain relays over Generalized-Gamma fading channels
K. P. Peppas, A. Mansour, G. S. Tombras
In this paper, a study on the end-to-end performance of dual-hop wireless communication systems equipped with fixed-gain relays and operating over Generalized-Gamma (GG) fading cha…
