This paper studies the performance of hybrid radio-frequency (RF) and free-space optical
(FSO) links assuming perfect channel state information (CSI) at the receiver. Considering the …

The cognitive radio (CR) paradigm has the potential of improving the exploitation of the
electromagnetic spectrum by detecting instantaneously unoccupied spectrum slots allocated …

We study the end-to-end (E2E) performance of multi-relay networks in delay-constrained
applications. The results are presented for both decode-and-forward (DF) and AF (A …

The Release 16 completion unlocks the road to an exciting phase pertain to the sixth
generation (6G) era. Meanwhile, to sustain far-reaching applications with unprecedented …

To mitigate spectrum scarcity, the cognitive radio (CR) paradigm has been invoked for
improving the overall exploitation of the licensed spectrum by identifying and filling the free …

First-order Marcum Q-function is observed in various problem formulations. However, it is
not an easy-to-handle function. For this reason, in this article, we first present a semi-linear …

This paper investigates the performance of cooperative relay networks in the presence of
hybrid automatic repeat request (ARQ) with delay constraint. It analyzes the scenarios where …

Incorporating relaying techniques into automatic repeat reQuest (ARQ) in general will
provide diversity and throughput enhancements. However, when opportunistic amplify-and …

In this letter, we present several cooperative incremental redundancy hybrid automatic
repeat request strategies for the slow-fading half-duplex time slotted multiple access multiple …

In this paper, the outage performance of hybrid automatic repeat request (hybrid-ARQ) over
a full-duplex decode-and-forward relay network is analyzed. Nakagami-m distribution is …
