Abstract

fetched live from OpenAlex

Recent wavelet research has primarily focused on real-valued wavelet bases. However, complex wavelet bases offer a number of potential advantageous properties. For example, it has been suggested that the complex wavelets can be used as a vestigial sideband (VSB) filter in multiuser communications C. J. Zarowski (2000). In this paper, we make an extension to the method of Davidson, Luo and Wongf (2000). We present a general method to design optimal complex-valued M-band filters and M-band wavelets. This method is more efficient and accurate than the previous linear programming problem (LPP) methods. And some examples of optimal wavelet design are provided. We also analyze the tradeoff between the peak stop band level (PSL) and stop band energy ratio (SER) of the optimal filters. Because this is important in designing waveforms with prescribed spectral characteristics.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
