Performance Analysis of LEO-Terrestrial Systems in Presence of Doppler Effect
Islam M. Tanash, Nuria Gonzalez-Prelcic, Risto Wichman
In this paper, we present a novel stochastic geometry-based approach to analyze the effect of residual Doppler shift on orthogonal frequency-division multiple access (OFDMA) system…
Statistical Modeling for Accurate Characterization of Doppler Effect in LEO-Terrestrial Networks
Islam M. Tanash, Risto Wichman, Nuria Gonzalez-Prelcic
Low Earth Orbit (LEO) satellite communication is a promising solution for global wireless coverage, especially in underserved and remote areas. However, the high relative velocity…
Urban RIS-Assisted HAP Networks: Performance Analysis Using Stochastic Geometry
Islam M. Tanash, Ayush Kumar Dwivedi, Taneli Riihonen
This paper studies a high-altitude platform (HAP) network supported by reconfigurable intelligent surfaces (RISs). The practical irregular placement of HAPs and RISs is modeled usi…
Integrating RIS into HAP Networks for Improved Connectivity
Islam M. Tanash, Ayush Kumar Dwivedi, Taneli Riihonen
This paper investigates a high-altitude platform (HAP) network enhanced with reconfigurable intelligent surfaces (RISs). The arbitrary placement of HAPs and RISs is modeled using s…
