A Novel Downlink IM-NOMA Scheme
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In the next generations of communication systems, resources' scarcity devolves to a more critical point as a consequence of the expected massive number of users to be served. Furthermore, the users' contradicting requirements ...
Novel selective OFDM-based cooperative techniques for multi-hop systems
(
Elsevier B.V.
, 2015 , Article)
In multi-hop systems, the theoretical outage probabilities and diversity orders of novel Orthogonal Frequency Division Multiplexing (OFDM) based Decode and Forward (DF) cooperative techniques are derived for different ...
Outage performance of incremental relaying networks with OFDM subcarriers mapping schemes
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
The scarcity of radio resources coupled with the high data rate demands in the last few years, induced incremental relaying techniques one of the most promising technologies. This is simply because it allows reaping spatial ...
Enhancing wireless networks performance through cooperative communications with interference management
(
IEEE
, 2012 , Conference Paper)
Cooperative radio communication has been proposed as an efficient technique to extend coverage and improve throughput in future wireless networks. However, its performance gain is degraded in the presence of co-channel ...
Modeling and analysis of HetNet interference using Poisson Cluster Processes
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Future mobile networks are converging towards being heterogeneous, owing to the co-existence of multi-tier networks within the same geographical area, including macro, pico- and femto-cells. The deployment of such networks ...
Performances analysis of SEC based transmit diversity systems with MRC receivers
(
IEEE
, 2012 , Conference Paper)
Switch and Examine combining (SEC) diversity scheme is one of the simplest yet efficient diversity schemes. Earlier in [1] and [2], we proposed sequential power loading algorithm to reduce the average power used at the ...
On the Performance of RIS-Assisted Dual-Hop UAV Communication Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In this paper, to further improve the coverage and performance of unmanned aerial vehicle (UAV) communication systems, we propose a reconfigurable intelligent surface (RIS)-assisted UAV scheme where an RIS installed on a ...
Modeling Heterogeneous Cellular Networks Interference Using Poisson Cluster Processes
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Future mobile networks are converging toward heterogeneous multitier networks, where macro-, pico-, and femto-cells are randomly deployed based on user demand. A popular approach for analyzing heterogeneous networks (HetNets) ...
Adaptive network coding for spectrum sharing systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose an adaptive network coding scheme for cognitive relay networks comprising multiple secondary sources communicating with a common destination in the presence of multiple primary users. Conventional ...
Improved relay selection for decode-and-forward cooperative wireless networks under secrecy rate maximization
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Privacy and security have an increasingly important role in wireless networks. A secure communication enables a legitimate destination to successfully retrieve information sent by a source, while it disables the eavesdropper ...
