Abstract

fetched live from OpenAlex

Among many proposed multi-carrier systems, circular filter bank multi-carrier offset quadrature amplitude modulation (CFBMC-OQAM) is one of promising candidates for future wireless networks. This paper studies the impacts of the intrinsic interferences, namely inter-symbol interference (ISI) and inter-carrier interference (ICI), and phase noise (PN) on the performance of CFBMC-OQAM systems. Two types of PN are considered: one is based on a free-running oscillator and the other is based on a phase-locked loop oscillator. Sources of performance degradation are quantified and a closed-form expression is derived for the signal-to-interference ratio (SIR). An algorithm is then applied to mitigate the PN impacts which takes into account the intrinsic interferences. It is observed that while the impact of the self interference can be negligible when there is no PN, the presence of PN significantly degrades performance of CFBMC-OQAM systems. The applied algorithm is shown to effectively remove the PN impacts.

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.
