State-Evolution-based Score Matching for Generalized Approximate Message Passing
Tomoharu Furudoi, Takumi Takahashi, Hideki Ochiai
Generalized approximate message passing (GAMP) equipped with minimum mean-square error (MMSE) denoisers, commonly referred to as Bayes-GAMP, is a powerful framework for solving inv…
Electromagnetic Digital Twin-Enabled Closed-Loop Beam Management in ISAC Systems
Yubin Luo, Takumi Takahashi, Li Yu +3
Digital twin (DT) is envisioned as a key enabler of sixth-generation (6G) communication systems, evolving from offline descriptive replicas for monitoring and analysis to inthe-loo…
Vector Similarity Search-Based MCS Selection in Massive Multi-User MIMO-OFDM
Fuga Kobayashi, Takumi Takahashi, Shinsuke Ibi +3
This paper proposes a novel modulation and coding scheme (MCS) selection framework that integrates mutual information (MI) prediction based on vector similarity search (VSS) for ma…
Reciprocity Calibration of Dual-Antenna Repeaters via MMSE Estimation
Shoma Hara, Takumi Takahashi, Hiroki Iimori +2
This paper proposes a novel Bayesian reciprocity calibration method that consistently ensures uplink and downlink channel reciprocity in repeater-assisted multiple-input multiple-o…
