Dual-Attention Based 3D Channel Estimation
Xiangzhao Qin, Sha Hu
For multi-input and multi-output (MIMO) channels, the optimal channel estimation (CE) based on linear minimum mean square error (LMMSE) requires three-dimensional (3D) filtering. H…

An Identity of Hankel Matrices Generated from the Moments of Gaussian Distribution
Sha Hu
In this letter, we proved a matrix identity of Hankel matrices that seems unrevealed before, generated from the moments of Gaussian distributions. In particular, we derived the Cho…

Reconfigurable AI Modules Aided Channel Estimation and MIMO Detection
Xiangzhao Qin, Sha Hu, Jiankun Zhang +2
Deep learning (DL) based channel estimation (CE) and multiple input and multiple output detection (MIMODet), as two separate research topics, have provided convinced evidence to de…
