Multiple Relay Selection and Beamforming in Dual-Hop Amplify-and-Forward Relay Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this paper, the problems of multiple relay selection and beamforming optimization are considered for a dual-hop amplify-and-forward relaying network under individual and total power constraints. The selection is performed ...
Security-Enhanced SC-FDMA Transmissions Using Temporal Artificial-Noise and Secret Key Aided Schemes
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
We investigate the physical-layer security of uplink single-carrier frequency-division multiple-access (SC-FDMA) systems. Multiple users, Alices, send confidential messages to a common legitimate base-station, Bob, in the ...
Time-Dependent Bit Error Rate Analysis for Smart Utility Networks in the Presence of WLAN Interferers
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
The smart grid (SG) modernizes the aging power grid by using two-way reliable communications dedicated to adaptive energy management. To achieve this goal, smart utility networks (SUNs) are used to efficiently connect the ...
Joint Frame Synchronization and Channel Estimation: Sparse Recovery Approach and USRP Implementation
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Correlation-based techniques used for frame synchronization can suffer significant performance degradation over multi-path frequency-selective channels. In this paper, we propose a joint frame synchronization and channel ...
On the delay/throughput-security tradeoff in wiretap TDMA networks with buffered nodes
(
IEEE
, 2019 , Article)
In this paper, we investigate the tradeoff between security and throughput and between security and queuing delay in wiretap time-division multiple access (TDMA) networks. We derive a simple relationship, characterized by ...
Exploiting Sparsity in Amplify-and-Forward Broadband Multiple Relay Selection
(
IEEE
, 2019 , Article)
Cooperative communication has attracted significant attention in the last decade due to its ability to increase the spatial diversity order with only single-antenna nodes. However, most of the techniques in the literature ...
Wiretap TDMA Networks with Energy-Harvesting Rechargeable-Battery Buffered Sources
(
IEEE
, 2019 , Article)
We investigate the physical-layer security of an uplink wireless time-division multiple-access channel with energy-harvesting source nodes. We consider a set of source nodes equipped with rechargeable batteries and information ...
