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…
Discrete-Valued Signal Estimation via Low-Complexity Message Passing Algorithm for Highly Correlated Measurements
Tomoharu Furudoi, Takumi Takahashi, Shinsuke Ibi +1
This paper considers a discrete-valued signal estimation scheme based on a low-complexity Bayesian optimal message passing algorithm (MPA) for solving massive linear inverse proble…
Channel Estimation and Equalization for CP-OFDM-based OTFS in Fractional Doppler Channels
Noriyuki Hashimoto, Noboru Osawa, Kosuke Yamazaki +1
Orthogonal time frequency and space (OTFS) modulation is a promising technology that satisfies high Doppler requirements for future mobile systems. OTFS modulation encodes informat…
Layered Belief Propagation for Low-complexity Large MIMO Detection Based on Statistical Beams
Takumi Takahashi, Antti Tölli, Shinsuke Ibi +1
This paper proposes a novel layered belief propagation (BP) detector with a concatenated structure of two different BP layers for low-complexity large multi-user multi-input multi-…
