Abstract
A novel complex-valued filter-bank design method, for generic multicarrier-modulation (MCM) systems with M-ary phase-shift keying (MPSK), is presented to minimise the symbol error rate (SER). The SER is evaluated by a newly derived closed-form formula, which can be used to evaluate both discrete-Fourier-transform (DFT)-based orthogonal-frequency-division-multiplexing (OFDM) and discrete-wavelet-multitone (DWMT) systems. Monte-Carlo numerical simulations are performed to verify the theoretical SER analysis and compare the error performance of the proposed MCM system with DFT-based OFDM and DWMT systems. It is shown that the derived formula is consistent with simulation results and the newly designed complex-valued filter-bank-based MCM system outperforms conventional DWMT systems in terms of the SER and has comparable SER performance with DFT-based OFDM systems with cyclic prefix (CP).

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
