Exploiting Sparsity in Amplify-and-Forward Broadband Multiple Relay Selection
(Institute of Electrical and Electronics Engineers Inc., 2019-05-01)
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 ...
Joint Frame Synchronization and Channel Estimation: Sparse Recovery Approach and USRP Implementation
(Institute of Electrical and Electronics Engineers Inc., 2019-03-25)
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 ...
Resource Allocation For Secure Wireless Powered Integrated Multicast and Unicast Services with Full Duplex Self-Energy Recycling
(Institute of Electrical Electronics Engineers Inc, 2019-01)
This paper investigates a secure wireless-powered integrated service system with full-duplex self-energy recycling. Specifically, an energy-constrained information transmitter (IT), powered by a power station (PS) in a ...
Wiretap TDMA Networks with Energy-Harvesting Rechargeable-Battery Buffered Sources
(Institute of Electrical and Electronics Engineers Inc, 2019-01-25)
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 ...
Security-Enhanced SC-FDMA Transmissions Using Temporal Artificial-Noise and Secret Key Aided Schemes
(IEEE-Inst Electrical Electronics Engineers Inc, 2019-01-19)
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 ...
