CaMPASS-Net: A Deep Learning Framework on Capacity Maximization for MIMO Pinching Antenna Systems in IoT
Bibliographic record
Abstract
pinching antenna system (PASS) has been demonstrated as a feasible flexible-antenna technology for upcoming 6G wireless networks and Internet of Things (IoT). In this article, we investigate a new design problem on capacity maximization for a point-to-point multiple-input–multiple-output (MIMO) PASS in a realistic IoT environment by jointly optimizing precoding matrix and antenna positioning. Unfortunately, this problem is not mathematically tractable. To break through this challenge in an effective and intelligent manner, we propose a novel and high-performing deep learning framework, named CaMPASS-Net, based on an advanced dual-stream network architecture with a residual connection, inspired by our insight into the problem. Furthermore, we present an effective unsupervised training strategy for the proposed CaMPASS-Net based on an innovative loss function design. Simulation results confirm that the proposed CaMPASS-Net exhibits remarkable performance improvements over baseline and existing schemes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
