Academic Integrity Review: "Hybrid Precoding Design for RSMA-Enabled LEO–ISAC Satellite System in PIoT" (IEEE TVT, DOI: 10.1109/TVT.2025.3567281)

Academic fraud report · Geng Detector

Summary

Verdict: No substantive indicators of academic misconduct were identified in this theoretical/simulation paper. The study by Liu, Wang, Du, Geng, and Zhao (IEEE Transactions on Vehicular Technology, Vol. 74, No. 10, 2025) was assessed across timeline, parameter plausibility, formula derivations, figure reuse, and statistical plausibility. The submission timeline (Received 21 Nov 2024; Revised 18 Mar 2025; Accepted 27 Apr 2025) is consistent and includes 2025-vintage references that plausibly entered during revision. Simulation parameters (600 km LEO altitude, 20 GHz, 15 MHz, Mt=36, Mr=16, 50 Monte Carlo runs) are physically reasonable. Formula derivations involving Schur complements, WMMSE, SROCR, DC, and CCP are internally coherent. Limits: This review is text-only and cannot perform pixel-level image forensics; absence of abnormal textual cues is not equivalent to proof of image authenticity.

Verdict

No misconduct indicators detected. Reviewed across five dimensions, the paper passes logical, parametric, and bibliographic checks. The case is recommended for closure subject to the caveat that high-resolution figures were not available for pixel-level inspection.

Key findings

Submission timeline (Received 21 Nov 2024, Revised 18 Mar 2025, Accepted 27 Apr 2025) is standard and internally consistent.
Citations published in 2025 (e.g., Ref. [11] April 2025; Ref. [23] January 2025) are logically absorbed during the Major Revision phase, not in the original submission.
Simulation setup uses physically reasonable LEO SATCOM parameters: altitude 600 km, carrier 20 GHz, bandwidth 15 MHz, arrays Mt=36, Mr=16.
Monte Carlo averaging set to 50 realizations—appropriate for heavy matrix-solver workloads (PDD, WMMSE, SROCR) and not implausibly inflated.
Reported RSMA gains over NOMA/SDMA align with established rate-splitting theoretical bounds; no anomalous discontinuities.
Derivations from the original problem through Schur complement augmentation, WMMSE reformulation, SROCR, and DC/CCP-based handling of the analog precoder F are continuous, with no unexplained equalities.
No biomedical or clinical statistics subject to p-hacking; numerical outputs are algorithmic results from convex solvers.

Authors: Xiaobo Liu, Xinru Wang, Fei Du, Suiyan Geng, Xiongwen Zhao
Venue: IEEE Transactions on Vehicular Technology, Vol. 74, No. 10 (2025)
Key simulation parameters (Section V): Mt=36, Mr=16, f=20 GHz, BW=15 MHz, LEO altitude=600 km, 50 channel realizations.
Mathematical framework spans Schur complement, WMMSE, SROCR, DC programming, and CCP.
Figures 2–8: convergence curves (OBJ/VIO), CRB vs. parameters, and beam-pattern heatmaps—formats typical of IEEE TVT simulation papers.

Notes

Image forensics are limited: only textual descriptions were available, so CFA noise, splicing edges, and copy-paste pixel reuse could not be examined. If a high-resolution PDF is later obtained, Figures 2–8 should be re-checked at the pixel level.
Theoretical papers inherently carry a higher threshold for detecting fabrication; therefore, the absence of textual anomalies here is a weak (though encouraging) signal and not a guarantee of image integrity.
