Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks
(
Springer International Publishing
, 2016 , Article)
In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to ...
Diversity-multiplexing tradeoff for log-normal fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Although there has been a growing interest on the study of diversity-multiplexing tradeoff (DMT), the existing works are mostly restricted to the outcomes reported for Rayleigh, Rician, and Nakagami fading channels. In ...
Relay selection schemes to minimise outage in wireless powered communication networks
(
Institution of Engineering and Technology
, 2016 , Article)
In this study, the authors discuss relay selection schemes with the objective to minimise outage probability for a network consisting of a single source, multiple relays and a single destination. The relays are powered by ...
On the effects of combined atmospheric fading and misalignment on the hybrid FSO/RF transmission
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Free-space optical (FSO) communication is known for its various impairments such as atmospheric turbulence and misalignment fading. In this paper, we study the performance of an FSO link operating under combined path loss ...
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 ...
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) ...
Optimal power allocation for relayed transmissions over Rayleigh-fading channels
(
IEEE
, 2004 , Article)
Relayed transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several shorter links/hops. One of the main advantages of this communication technique ...
A novel energy harvesting scheme for mixed fso-rf relaying systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this correspondence paper, we consider the performance of a mixed free-space optical and radio frequency (FSO-RF) relaying system with energy harvesting in the existence of both atmospheric turbulence and pointing errors. ...
