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…
Path Loss, Angular Spread and Channel Sparsity Modeling for Indoor and Outdoor Environments at the sub-THz Band
Dimitrios G. Selimis, Mar Francis De Guzman, Fotis I. Lazarakis +3
In this paper, we present new measurement results to model large-scale path loss, angular spread and channel sparsity at the sub-THz (141-145 GHz) band, for both indoor and outdoor…
On the Distribution of the Ratio of Products of Fisher-Snedecor Random Variables and Its Applications
Hongyang Du, Jiayi Zhang, Kostas P. Peppas +3
The Fisher-Snedecor distribution has been recently proposed as a more accurate and mathematically tractable composite fading model than traditional established models…
Physical Layer Security over Fluctuating Two-Ray Fading Channels
Wen Zeng, Jiayi Zhang, Shuaifei Chen +2
Ensuring the physical layer security (PHY-security) of millimeter wave (mmWave) communications is one of the key factors for the success of 5G. Recent field measurements show that…
New Results on the Fluctuating Two-Ray Model with Arbitrary Fading Parameters and Its Applications
Jiayi Zhang, Wen Zeng, Xu Li +2
The fluctuating two-ray (FTR) fading model provides a much better fit than other fading models for small-scale fading measurements in millimeter wave communications. In this paper,…
Secrecy Outage Analysis over Correlated Composite Nakagami-/Gamma Fading Channels
George C. Alexandropoulos, Kostas P. Peppas
The secrecy outage performance of wireless communication systems operating over spatially correlated composite fading channels is analyzed in this paper. We adopt a multiplicative…
A Unified Effective Capacity Performance Analysis of Lp-norm Diversity Reception over Arbitrary and Correlated Generalized Fading Channels
K. Denia Kanellopoulou, Kostas P. Peppas, P. Takis Mathiopoulos
The effective capacity (EC) has been recently established as a rigorous alternative to the classical Shannon's ergodic capacity since it accounts for the delay constraints imposed…
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…
