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 ...
Machine-Learning Based Relay Selection in AF Cooperative Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
With the significant increase of wireless network nodes and traffic load in recent years, especially in the emerging internet-of-things (IoT) and vehicular networks, the design of a fast adaptive relay selection algorithm ...
Sparse Equalizers for OFDM Signals with Insufficient Cyclic Prefix
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
The cyclic prefix (CP) is appended in orthogonal frequency division multiplexing (OFDM) signals to combat inter-symbol interference (ISI) and inter-carrier interference (ICI) induced by the communication channel, which ...
Deterministic measurement procedures for diagnosis of massive uniform linear antenna arrays
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
The number and relative geometry of collected measurements significantly affect the reliability of massive antenna array diagnosis. In this paper, we investigate and compare two deterministic algorithms for taking measurements ...
A Secret-key-aided scheme to secure transmissions from single-antenna RF-eh source nodes
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
We propose a two-phase artificial-noise-aided scheme to power a single-antenna energy-harvesting source node (Alice) and secure her transmissions to a multiple-antenna legitimate destination (Bob) in the presence of a ...
Impact of Passive and Active Security Attacks on MIMO Smart Grid Communications
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
We consider multiple source nodes (consumers) communicating wirelessly their energy demands to the meter data-management system (MDMS) over the subarea gateway(s). We quantify the impact of passive and active security ...
Relay selection in FDD amplify-and-forward cooperative networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In this paper, the problems of relay selection and distributed beamforming are investigated for bi-directional dual-hop amplify-and-forward frequency-division duplex cooperative wireless networks. When using individual ...
OFDM Full-Duplex DF Relaying under I/Q Imbalance and Loopback Self-Interference
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
We analyze the outage probability of dual-hop full-duplex (FD) decode-and-forward (DF) relaying for an orthogonal frequency-division multiplexing (OFDM) system in the presence of in-phase and quadrature-phase (I/Q) imbalance ...
Sparsity-aware narrowband interference mitigation and subcarriers selection in OFDM-based cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, the performance of an orthogonal frequency division multiplexing overlay cognitive radio network with subcarrier selection schemes is investigated. We propose three subcarrier selection techniques that reduce ...
A sparsity-aware approach for NBI estimation and mitigation in large cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the coverage area. Therefore, in this ...
