We consider three-node wireless relay channels in a Rayleigh-fading environment.
Assuming transmitter channel state information (CSI), we study upper bounds and lower …

This paper presents theoretical characterizations and analysis for the physical layer of
multihop wireless communications channels. Four channel models are considered and …

In this tutorial, the design procedure of near-capacity channel code design invoking non-
binary EXtrinsic Information Transfer (EXIT) charts is illustrated by using design examples of …

In this paper, we consider the power splitting relaying (PSR) and time switching relaying
(TSR) protocols for decode-and-forward (DF)-based relay networks consisting of a source, a …

Unmanned-aerial-vehicles (UAVs) are intended to be a vital part of beyond 5G (B5G) and
6G communication networks. UAV-to-ground communications in urban and populated areas …

Second order statistics provides a dynamic representation of a fading channel and plays an
important role in the evaluation and design of the wireless communication systems. In this …

A multihop transmission scheme is proposed and studied, where all the relay nodes (RNs)
of a multihop link are assumed to have buffers for temporarily storing their received packets …

This paper presents an analytical methodology for the evaluation of two important physical
layer security metrics in wiretap channels. Specifically, we first introduce the concept and the …

An advantage of using the composite fading models (CFMs) is their ability to concurrently
address the impact of multi-path and shadowing phenomena on the system performance in …

The level crossing rate (LCR) and the average outage duration (AOD) are two important
second order statistics that allow a deeper understanding of the behavior of the channel. In …
