Estimating the number of sources in white Gaussian noise: Simple eigenvalues based approaches
(
Institution of Engineering and Technology
, 2017 , Article)
Estimating the number of sources is a key task in many array signal processing applications. Conventional algorithms such as Akaike's information criterion (AIC) and minimum description length (MDL) suffer from underestimation ...
On the Achievable Rates of OFDM with Common Phase Error Compensation in Phase Noise Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper considers the problem of analytically assessing the maximum achievable rates (capacity) of orthogonal frequency division multiplexing (OFDM) transmissions when the receiver, for complexity reasons, only accounts ...
A Distributed Approach for Networked Flying Platform Association with Small Cells in 5G+ Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
The densification of small cell base stations in a 5G architecture is a promising approach to enhance the coverage area and facilitate the ever increasing capacity demand of end users. However, the bottleneck is an intelligent ...
Dynamic interference-limited relay sharing in cognitive radio networks by using hierarchical modulation
(
Institution of Engineering and Technology
, 2017 , Article)
Sharing a relay in cognitive radio (CR) networks in order to enhance the secondary user's (SU's) performance in an interference-limited scheme is investigated. It is assumed, by utilising hierarchical modulation, a shared ...
Swinging with the Jet Set: Analysis of Electromagnetic Fields Inside Jet Engines - From Numerical and Experimental Analysis to Statistical Analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Analyzing electromagnetic propagation inside jet engine turbines is a challenging and important research topic due to its potential applications in both civil and military fields. Electromagnetic modeling of such complex ...
On the coexistence of a primary user with an energy harvesting secondary user: A case of cognitive cooperation
(
John Wiley and Sons Ltd
, 2016 , Article)
In this paper, we consider a cognitive scenario where an energy harvesting secondary user shares the spectrum with a primary user. The secondary source helps the primary source in delivering its undelivered packets during ...
Reinforcement learning-based decision support system for COVID-19
(
Elsevier
, 2021 , Article)
Globally, informed decision on the most effective set of restrictions for the containment of COVID-19 has been the subject of intense debates. There is a significant need for a structured dynamic framework to model and ...
Smart System to Monitor Social-Distancing During the Covid-19 Pandemic
(
Qatar University Press
, 2020 , Poster)
We introduce a smart system to track and maintain real-time physical distance between people and to warn people to any deviation from the prescribed distances. Social-distancing is an effective way of slowing infectious ...
Novel hybrid physical layer security technique in RFID systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
In this paper, we propose a novel PHY layer security technique in radio frequency identification (RFID) backscatter communications system. In order to protect the RFID tag information confidentiality from the eavesdroppers ...
On correlation-based channel sensing with IQ imbalance
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
This paper addresses the problem of the detection of the presence of a pre-classified (i.e., pulse shape is known) signals with IQ imbalance considering free-space path-loss. We study the effect of IQ distortion on the ...
