Purpose of the book and editorial perspectives
(
Springer International Publishing
, 2015 , Book chapter)
Engineering and engineering education play an essential role in the Middle East. Global debates regarding roles of engineering and required transformations in engineering education have been extensive during the past few ...
On Optimizing the Secrecy Performance of RIS-Assisted Cooperative Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Employing reconfigurable intelligent surfaces (RIS) is emerging as a game-changer candidate, thanks to their unique capabilities in improving the power efficiency and supporting the ubiquity of future wireless communication ...
Performance analysis of best relay selection scheme for fixed gain cooperative networks in non-identical Nakagami-m channels
(
IEEE
, 2010 , Conference Paper)
Selecting the best relay among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay cooperation. This scheme also achieves the ...
On the capacity of cooperative diversity systems with adaptive modulation
(
IEEE
, 2005 , Conference Paper)
In recent years, cooperative diversity systems have gained increased attention in the literature as a new way of combating the effect of signal fading. In this paper, we investigate the performance of these systems when ...
Dynamic optimization of LTE pilot scattering based on channel estimation
(
IEEE
, 2012 , Conference Paper)
A dynamic optimization of the pilot scattering for Long Term Evolution (LTE) downlink system is introduced. This optimization is based on channel parameters estimations to optimize the number of pilots used in the transmission ...
Joint statistics of partial sums of ordered exponential variates and performance of GSC RAKE receivers over rayleigh fading channel
(
IEEE
, 2011 , Article)
Spread spectrum receivers with generalized selection combining (GSC) RAKE reception were proposed and have been studied as alternatives to the classical two fundamental schemes: maximal ratio combining and selection combining ...
Performance analysis of relay selection schemes in OFDM-based underlay cognitive networks
(
IEEE
, 2013 , Conference Paper)
Cognitive radio (CR) is a promising technology that allows wireless systems to sense the environment and learn from previous experience to improve the communication quality. However, CR needs a flexible and adaptive physical ...
User cooperation schemes in the soft handover regions
(
IEEE
, 2009 , Conference Paper)
This paper examines the effect of relay-assisted soft handover on the performance of the uplink communication in the third generation mobile networks. We focus on users which are traveling over two cell boundaries in a ...
Full-Duplex Amplify-and-Forward Relaying under I/Q Imbalance
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
A major performance limiter in amplify-and-forward (AF) full-duplex (FD) relaying is the high level of residual self-interference (SI) due to the imperfect estimation of the effective self-interfering channel. One primary ...
Outage performance of cooperative systems under IQ imbalance
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
In this contribution, we investigate the outage performance of OFDM-based Decode and Forward (DF), Amplify and Forward (AF) and Controlled DF (CDF) cooperative systems under IQ Imbalance (IQI). In particular, tractable and ...
