Abstract
Recently, the growing popularity of low-complexity multi-carrier modulation techniques, such as orthogonal frequency division multiplexing (OFDM), has led researchers to consider equalization of single carrier (SC) transmissions in the frequency domain. However, existing frequency domain equalizers for single carrier modulation rely on the introduction of a cyclic prefix (CP), which are usually not available in the conventional SC based communications standards. In this paper, a frequency domain equalizer (FEQ) without cyclic prefix for single carrier system is proposed. An interference analysis is presented for the block equalization of SC system without CP. The cancellation of the inter-block interference and inter-carrier interference are based on the proposed iterative interference cancellation. The proposed equalizer and the subsequent analysis are also verified through numerical simulations.

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
