Detection of Transmitted Power Violation Based on Geolocation Spectrum Database in Satellite-Terrestrial Integrated Networks

Sensors, 2020
This paper investigates the detection of the transmitted power violation (TPV) in the satellite-terrestrial integrated network, where the terrestrial base station may break the spectrum policies so that severe damages are made to the satellite systems ...

Generalized fiducial methods for testing quantitative trait locus effects in genetic backcross studies

Statistical Theory and Related Fields, 2022
In this paper, we propose generalized fiducial methods and construct four generalized p-values to test the existence of quantitative trait locus effects under phenotype distributions from a location-scale family.

Statistical test for GNSS spoofing attack detection by using multiple receivers on a rigid body

EURASIP Journal on Advances in Signal Processing, 2020
Global navigation satellite systems (GNSS) are being the target of various jamming, spoofing, and meaconing attacks. This paper proposes a new statistical test for the presence of multiple spoofers based on range measurements observed by a plurality of ...

Sequential Generalized Likelihood Ratio Tests for Online Item Monitoring

Psychometrika, 2021
The study presents statistical procedures that monitor functioning of items over time. We propose generalized likelihood ratio tests that surveil multiple item parameters and implement with various sampling techniques to perform continuous or intermittent monitoring.

Detection of Spectrum Misuse Behavior in Satellite-Terrestrial Spectrum Sensing Based on Multi-Hypothesis Tests

IEEE Access, 2020
As the increasing of both users' demand and the number of communication satellites, spectrum resource is becoming increasingly scarce. Cognitive radio (CR) can effectively alleviate the scarcity of spectrum resource.

Spectrum Sharing Between Radar and Communication Systems Based on Overlapped Virtual Subarrays

IEEE Access, 2022
In this paper, we propose a new technique for spectrum sharing between radar and communication systems. The new technique enjoys the advantages of null-space projecting which can be used to mitigate the interference between radar and communication ...

Estimation of Stress-Strength Reliability for Multicomponent System with Rayleigh Data

Energies, 2021
Inference is investigated for a multicomponent stress-strength reliability (MSR) under Type-II censoring when the latent failure times follow two-parameter Rayleigh distribution. With a context that the lifetimes of the strength and stress variables have

Bivariate Discrete Modified Weibull (BDMW) Distribution

Statistica, 2021
In this paper we develop a bivariate discrete modifiedWeibull (BDMW) distribution and derived some of its important properties such as joint survival function, marginal survival function, conditional survival function, joint probability generating ...
