Wavefront Transformation-based Near-field Channel Prediction for Extremely Large Antenna Array with Mobility
Weidong Li, Haifan Yin, Ziao Qin +1
This paper addresses the mobility problem in extremely large antenna array (ELAA) communication systems. In order to account for the performance loss caused by the spherical wavefr…
Low-complexity eigenvector prediction-based precoding matrix prediction in massive MIMO with mobility
Ziao Qin, Haifan Yin, Weidong Li
In practical massive multiple-input multiple-output (MIMO) systems, the precoding matrix is often obtained from the eigenvectors of channel matrices and is challenging to update in…
A manifold learning-based CSI feedback framework for FDD massive MIMO
Yandi Cao, Haifan Yin, Ziao Qin +3
Massive multi-input multi-output (MIMO) in Frequency Division Duplex (FDD) mode suffers from heavy feedback overhead for Channel State Information (CSI). In this paper, a novel man…
A review of codebooks for CSI feedback in 5G new radio and beyond
Ziao Qin, Haifan Yin
Codebooks have been indispensable for wireless communication standard since the first release of the Long-Term Evolution in 2009. They offer an efficient way to acquire the channel…
