Hybrid Full-Duplex and Alternate Multiple Relay Selection and Beamforming in AF Cooperative Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, multiple relay selection and beamforming techniques are applied to a dual-hop full-duplex (FD) amplify-and-forward relaying network. We show that our proposed techniques allow the selection to be adaptive ...
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 ...
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 ...
Efficient techniques for energy saving in data center networks
(
Elsevier B.V.
, 2018 , Article)
Data centers are constructed with a huge number of network devices to support the expanding cloud based services. These devices are used to achieve the highest performance in case of full utilization of the network. However, ...
Secondary users selection and sparse narrow-band interference mitigation in cognitive radio networks
(
Elsevier B.V.
, 2018 , Article)
Spectrum scarcity is a critical problem that may reduce the effectiveness of wireless technologies and services. To address this problem, different spectrum management techniques have been proposed in the literature such ...
