Abstract
This paper presents a secure Multi-Carrier Differential Chaos Shift Keying (MC-DCSK) system. This hybrid of MC modulation and DCSK is aimed at combining the height data rate, the simplified equalization in multipath propagation, the robustness to impulse noise, and the security of transmission coming from the use of chaotic signals in digital communications. In this paper, we describe the proposed transmitter and receiver, including the chaotic modulation used in a single input, single output system, and then we evaluate the potential benefits of the MC-DCSK. To increase security, a spreading and interleaving in time and frequency are used to break the similarity between the reference and the data samples of the DCSK signal. The performance of the MC-DCSK is evaluated under a fading communication channel, and without equalization on the receiver side. An approach for computing the bit-error-rate (BER) performance is provided, and an analytical BER expression is derived. Simulation results confirm the accuracy of our performance computation approach.

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 it
