The paper explores N-hop FSO communications assisted by amplify-and-forward relays
(AFRs) over N-gamma-gamma (N-gg) turbulence induced (TI) fading channels. We model TI …

To expedite research progress on terahertz (THz) communications, we analyze the outage
performance of THz communication systems by a compound channel model in this paper …

Terahertz (THz) wireless technology is envisioned to enable terabit-per-second (Tbps) and
secure transmissions in sixth-generation (6G) communication networks and has attracted …

In this article, we develop an innovative series representation for the sum of Rician non-zero
boresight pointing error random variates based on the distribution, which is suitable for …

Radio frequency (RF) spectrum is already dense enough and hard to add more broadband
channels to meet the current user demands. Optical free-space communications could be an …

To promote the applications of gamma approximation for lognormal shadowing models in a
multitude of applications, we propose to use the Kolmogorov-Smirnov (KS) criterion to …

Many fish species form social aggregations or shoals. Understanding the conditions under
which these groups sometimes coordinate their behavior in space and time, or “school,” is …

In this paper, we develop a novel moment-based approach for the evaluation of the outage
probability (OP) in a generalized fading environment with interference and noise. Our …

In this letter, we study the information-theoretic optimality of the gamma approximation for
lognormal shadowing models in order to provide a rigorous mathematical ground for this …

Channel model substitution (CMS) is an analytical technique aiming to replace a
computationally complex channel model with a simpler substitute. The utility of CMS is …
