Soft Graph Diffusion Transformer for MIMO Detection
Nan Jiang, Jiadong Hong, Lei Liu +3
Learning-based MIMO detection has shown strong empirical performance, yet existing methods typically rely on fixed-depth architectures without explicitly modeling the progressive r…
Interleaved Block-Sparse Transform
Lei Liu, Ming Wang, Shufeng Li +3
Low-complexity Bayes-optimal memory approximate message passing (MAMP) is an efficient signal estimation algorithm in compressed sensing and multicarrier modulation. However, achie…
Interleave Frequency Division Multiplexing
Yuhao Chi, Lei Liu, Yao Ge +3
In this letter, we study interleave frequency division multiplexing (IFDM) for multicarrier modulation in static multipath and mobile time-varying channels, which outperforms ortho…
Memory AMP for Generalized MIMO: Coding Principle and Information-Theoretic Optimality
Yufei Chen, Lei Liu, Yuhao Chi +2
To support complex communication scenarios in next-generation wireless communications, this paper focuses on a generalized MIMO (GMIMO) with practical assumptions, such as massive…
Low-Complexity and Information-Theoretic Optimal Memory AMP for Coded Generalized MIMO
Yufei Chen, Lei Liu, Yuhao Chi +2
This paper considers a generalized multiple-input multiple-output (GMIMO) with practical assumptions, such as massive antennas, practical channel coding, arbitrary input distributi…
