B13 Processor – Residual-to-Bias Feedback with Stability Constraints (Work in Progress)
Abstract
This note describes an experimental architectural concept called the B13 Processor.
Unlike classical FFT-based processing, which performs linear basis decomposition,
the B13 architecture treats internal residual energy ("heat", H) not as waste,
but as a structured control signal.
This document focuses on one specific mechanism:
Error-to-Bias Feedback (H-Carrier)
with explicit stability constraints.
This is an engineering-oriented draft (Ver 0.9).
1. Motivation
In most signal processing pipelines:
- Residual error is discarded.
- Noise is suppressed or filtered out.
- Adaptation requires explicit learning.
The B13 approach proposes a different viewpoint:
Residual energy (H) may contain unresolved structural information.
Instead of discarding it,
we convert it into a bounded adaptive bias for the next stage.
2. H-Carrier Concept
Each unit produces:
- Primary signal outputs (I/Q or equivalent)
- Residual outputs:
- H_s (signed residual)
- H_m (residual magnitude)
The residual is processed through:
- Threshold gating
- Leaky integration
- Loop-gain constraint
Only after satisfying these conditions is it reinjected.
3. Stability Constraints
3.1 Threshold Gate
Small residuals (noise floor level) must not circulate.
Let:
- τ = noise floor threshold
- κ = soft-gate slope
Gate coefficient:
