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…
Asynchronous Grant-Free Random Access: Receiver Design with Partially Uni-Directional Message Passing and Interference Suppression Analysis
Zhaoji Zhang, Yuhao Chi, Qinghua Guo +3
Massive Machine-Type Communications (mMTC) features a massive number of low-cost user equipments (UEs) with sparse activity. Tailor-made for these features, grant-free random acces…
Generalized Linear Systems with OAMP/VAMP Receiver: Achievable Rate and Coding Principle
Lei Liu, Yuhao Chi, Ying Li +1
The generalized linear system (GLS) has been widely used in wireless communications to evaluate the effect of nonlinear preprocessing on receiver performance. Generalized approxima…
