Design of a Novel Time Index Modulation DCSK Wireless-Powered System
Bibliographic record
Abstract
In this paper, we propose a new time index modulation (TIM)-based differential chaos shift keying (TIM-DCSK) wireless-powered system. Specifically, we design a time-slot transmission frame, where one time slot is used to carry a bit for wireless information transmission (WIT), while the remaining time slots are used for wireless-powered transmission (WPT). Furthermore, additional index bits for WIT can be transmitted according to the position of the time slot. The results reveal that the proposed system enhances time-slot use, thereby enabling efficient information transfer and energy harvesting for self-sustainability. In addition, we dervie the bit error rate (BER) expression of the WIT for the proposed system and analyze the closed-form energy-shortage probability of the WPT over multipath Rayleigh fading channels. The results reveal that the proposed system achieves better performance as compared to the power-splitting (PS)-based DCSK (PS-DCSK) and time-switching (TS)-based DCSK (TS-DCSK) systems.

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.
