Abstract

fetched live from OpenAlex

This paper demonstrates the application of a high-order finite-difference time-domain (FDTD) technique to indoor microwave ultrawideband channel modeling with a two-fold purpose. First, the advantages of both serial and parallel versions of the technique compared to the conventional FDTD are pointed out. It is also shown that the results of this full-wave analysis can be translated from the electromagnetic field level to the system level, to produce simplified, physics-based, site-specific channel models. In particular, the parameters of well-established measurement-based models are determined for a specific indoor site, by means of our electromagnetic simulation. Moreover, the proposed technique is coupled with the Monte-Carlo method to characterize the capacity of a time-hopping pulse position modulation multiple access system. Hence, a connection between the field analysis of a channel and its system-level description is made, establishing the usefulness of this work for performance projections, optimization and compatibility studies of ultrawideband communication schemes and network architectures.

Full frame distilled prediction

Teacher imitation

Not 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.
