Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this article, we investigate the security of a cognitive satellite-terrestrial network that seamlessly integrates simultaneous wireless information and power transfer (SWIPT). The network comprises a secondary system that employs the sophisticated multiple-input multiple-output SWIPT technology. Within shared spectrum, the secondary network's primary objective is to transmit confidential messages to a legitimate receiver (Bob), all the while providing energy to multiple energy receivers, which may act as eavesdroppers. Beamforming techniques and artificial noise schemes are employed to enhance transmission specifically to Bob. The ergodic secrecy capacity (ESC) with the Gauss-Laguerre quadrature approximation method is analyzed. Moreover, the asymptotic results for ESC are investigated including the slope and power offset under high signal-to-noise ratios. Finally, Monte Carlo simulations are presented to affirm the precision and accuracy of the derived analytical models and the proposed analysis.
