Optimal Processing of an Impulse Radio Signal Subjected to Narrow Band Interference
Bibliographic record
Abstract
Ultra wide band (UWB) links are inherently subject to narrowband interference (NBI) from other narrowband communication links. An UWB receiver architecture that is proven effective in mitigating NBI sources is the analog filter bank (AFB) followed by a generalized matched filter (GMF) processing as introduced in J. Nielsen et al. (2004) and R. Pasand et al. (2004). In this paper, a further development of this architecture is developed, which introduces two and three level quantization (2LQ, 3LQ) for the required sampling at the output of the AFB instead of multibit linear quantization (LQ). This substantially reduces the implementation complexity of the UWB receiver as well as the computational effort required. Simulation of the AFB receiver with 2LQ, 3LQ is given in this paper, which shows the remarkable observation that the performance loss attributed to this crude quantization is negligible.

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.
