Joint random subcarrier selection and channel-based artificial signal design aided PLS
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
A novel method for providing physical layer security (PLS) depending on the randomness of wireless channel is proposed. Specifically, a channel-based joint random subcarrier selection and artificial signal design are ...
NOMA with Index modulation for uplink URLLC through grant-free access
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper proposes non-orthogonal sharing of available resources between latency-critical and latency-tolerant communication for fulfilling tight requirements of ultra-reliable low-latency communication (URLLC) as well ...
An OFDM signal identification method for wireless communications systems
(Institute of Electrical and Electronics Engineers, 2015)
Distinction of orthogonal frequency-division multiplexing (OFDM) signals from single-carrier signals is highly important for adaptive receiver algorithms and signal identification applications. OFDM signals exhibit Gaussian ...
Rf circuit implementation of a real-time frequency spread emulator
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
Despite their reliability, on-site measurements are time-consuming and costly actions for the evaluation of new devices. Channel emulators are widely utilized measurement instruments to generate desired environmental channel ...
Partially overlapping tones for uncoordinated networks
(Institute of Electrical and Electronics Engineers, 2014)
In an uncoordinated network, the link-level performance of a wireless receiver might degrade significantly due to the interference from other transmitters that share the same spectrum. As a solution, in this study, the ...
Suppressing alignment: Joint PAPR and out-of-band power leakage reduction for OFDM-based systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2016)
Orthogonal frequency division multiplexing (OFDM) inherently suffers from two major drawbacks: high out-of-band (OOB) power leakage and high peak-to-average power ratio (PAPR). This paper proposes a novel approach called ...
A novel biasing technique for low phase noise voltage controlled oscillators
(Elsevier Sci Ltd., 2018)
This paper proposes a new biasing technique for LC-based voltage controlled oscillators to improve the phase noise performance while ensuring the current variations to be within an acceptable range. The proposed technique ...
Joint subcarrier and antenna state selection for cognitive heterogeneous networks with reconfigurable antennas
(Institute of Electrical and Electronics Engineers, 2015)
Reconfigurable antennas (RA) offer an emerging technology that allows wireless devices to alter their antenna states determined by different radiation patterns to maximize received signal strength. In this paper, we consider ...
A windowing technique for optimal time-frequency concentration and aci rejection in ofdm-based systems
