Secrecy Outage Performance Analysis for Cooperative NOMA Over Nakagami-
IEEE Access, 2019 In this paper, we investigate the secrecy outage performance of a typical cooperative downlink non-orthogonal multiple access (NOMA) system over Nakagami-m fading channel, in which the base station transmits a superimposed signal to two users via a relay.

Forgoing Nuclear: Nuclear Power Plant Closures and Carbon Emissions in the United States
Southern Economic Journal, EarlyView.ABSTRACT This paper examines the effect of nuclear power plant decommissioning on electricity generation and carbon emissions in the United States. Using data on nuclear reactor closures in the United States between 1993 and 2022 and data on state‐level carbon emissions and electricity generation from the Energy Information Administration (EIA), this ...

Robust Power Allocation and Outage Analysis for Secrecy in Independent Parallel Gaussian Channels
, 2015 This letter studies parallel independent Gaussian channels with uncertain eavesdropper channel state information (CSI). Firstly, we evaluate the probability of zero secrecy rate in this system for (i) given instantaneous channel conditions and (ii) a ...

Secrecy Outage Probability Fairness for Intelligent Reflecting Surface-Assisted Uplink Channel
, 2022 This paper investigates physical layer security (PLS) in the intelligent reflecting surface (IRS)-assisted multiple-user uplink channel. Since the instantaneous eavesdropper's channel state information (CSI) is unavailable, the secrecy rate can not be measured.

British Journal of Special Education, EarlyView.Abstract Parents of children with special needs in Nigeria are faced with several challenges. In most cases, decisions are taken without their active involvement, despite them being the primary carers for their children with special needs. This research utilised a qualitative research design with fifteen participants to understand parents' perspectives

Jamming-Aided Secure Communication in Massive MIMO Rician Channels
, 2015 In this paper, we investigate the artificial noise-aided jamming design for a transmitter equipped with large antenna array in Rician fading channels. We figure out that when the number of transmit antennas tends to infinity, whether the secrecy outage ...
