B13 Processor – Residual-to-Bias Feedback with Stability Constraints (Work in Progress)

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:

  1. Threshold gating
  2. Leaky integration
  3. 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:
