A General Analytical Approach for Outage Analysis of HARQ-IR over Correlated Fading Channels [PDF]

open access: yesarXiv, 2022
This paper proposes a general analytical approach to derive the outage probability of hybrid automatic repeat request with incremental redundancy (HARQ-IR) over correlated fading channels in closed-form. Unlike prior analyses, the consideration of channel correlation is one of the key reasons making the outage analysis involved.

A Fluid Model for Performance Analysis in Cellular Networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
We propose a new framework to study the performance of cellular networks using a fluid model and we derive from this model analytical formulas for interference, outage probability, and spatial outage probability.

Evaluation of Compact Boundary of Outage Probability in HetNet [PDF]

open access: yesWireless Communications and Mobile Computing, 2021
In this paper, we investigate the outage probability of per‐tier in heterogeneous networks (HetNet) in the presence of aggregated interference from coexisting ad hoc networks. In ad hoc networks, a receiving node suffers the cross‐tier interference signal from cellular cell and aggregated interference signal from other transmitting nodes.

Minimizing the Outage Probability in a Markov Decision Process

open access: yes2023 IEEE Information Theory Workshop (ITW), 2023
Standard Markov decision process (MDP) and reinforcement learning algorithms optimize the policy with respect to the expected gain. We propose an algorithm which enables to optimize an alternative objective: the probability that the gain is greater than a given value. The algorithm can be seen as an extension of the value iteration algorithm.

UAV-enabled reliable mobile relaying under the time-varying Rician fading channel

open access: yesAlexandria Engineering Journal, 2023
This paper adopts an unmanned aerial vehicle (UAV) relay to forward data from a source sensor to a remote base station (BS). To ensure reliable data transmission, our objective is to minimize the average outage probability along the three-dimensional (3D)

Modeling Analysis for Downlink RIS-UAV-Assisted NOMA over Air-to-Ground Line-of-Sight Rician Channels

open access: yesDrones
This paper proposes a drone-assisted NOMA communication system equipped with a reconfigurable intelligent surface (RIS). Given the Line-of-Sight nature of the Air-to-Ground link, a more realistic Rician fading environment is chosen for the study of ...

Security versus Reliability Analysis of Opportunistic Relaying

open access: yes, 2013
Physical-layer security is emerging as a promising paradigm of securing wireless communications against eavesdropping between legitimate users, when the main link spanning from source to destination has better propagation conditions than the wiretap link

MIMO Relay Networks: Scheduling and Outage Probability

open access: yesIEEE Wireless Communications Letters, 2019
We study a dual-hop multiple-input multiple-output (MIMO) relay network where the traffic source uses a relay node, selected among several possible ones, to serve multiple users. Considering that the nodes deployment can be described by Poisson point processes in a sector area, we derive the distribution of the signal-to-interference-plus-noise ratio ...

Leaf, plant, to canopy: A mechanistic study on aboveground plasticity and plant density within a maize–soybean intercrop system for the Midwest, USA

open access: yesPlant, Cell &Environment, Volume 46, Issue 2, Page 405-421, February 2023., 2023
Abstract Plants have evolved to adapt to their neighbours through plastic trait responses. In intercrop systems, plant growth occurs at different spatial and temporal dimensions, creating a competitive light environment where aboveground plasticity may support complementarity in light‐use efficiency, realizing yield gains per unit area compared with ...
