Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper investigates the impact of practical limitations, such as transceiver hardware impairments and channel state information mismatch, on a cognitive hybrid satellite-terrestrial relay network.Moreover, it is assumed that the network is under the effect of independent and non-identically distributed interference noises emerging from neighboring device nodes.Generalized closed-form expressions of ergodic capacity for a terrestrial user are obtained considering the interference temperature constraint's influence.Finally, derived findings are validated through Monte Carlo simulation and the impact of impairments is examined.
