Three-Module SC-VAMP for LDPC-Coded Nonlinear Channels
Tadashi Wadayama, Takumi Takahashi
We propose a three-module extension of score-based VAMP (SC-VAMP) for signal recovery in nonlinear channels, where the received signal is obtained by applying a nonlinearity to a l…
Score-Based VAMP with Fisher-Information-Based Onsager Correction
Tadashi Wadayama, Takumi Takahashi
We propose score-based VAMP (SC-VAMP), a variant of vector approximate message passing (VAMP) in which the Onsager correction is expressed and computed via conditional Fisher infor…
Physics-Aware Decoding for Communication Channels Governed by Partial Differential Equations
Tadashi Wadayama, Koji Igarashi, Takumi Takahashi
Digital communication systems inherently operate through physical media governed by partial differential equations (PDEs). In this paper, we introduce a physics-aware decoding fram…
Physics-Aware Sparse Signal Recovery Through PDE-Governed Measurement Systems
Tadashi Wadayama, Koji Igarashi, Takumi Takahashi
This paper introduces a novel framework for physics-aware sparse signal recovery in measurement systems governed by partial differential equations (PDEs). Unlike conventional compr…
