Compressed CPD-Based Channel Estimation and Joint Beamforming for RIS-Assisted Millimeter Wave Communications
Xi Zheng, Jun Fang, Hongwei Wang +2
We consider the problem of channel estimation and joint active and passive beamforming for reconfigurable intelligent surface (RIS) assisted millimeter wave (mmWave) multiple-input…
Spatial Channel Covariance Estimation and Two-Timescale Beamforming for IRS-Assisted Millimeter Wave Systems
Hongwei Wang, Jun Fang, Huiping Duan +1
We consider the problem of spatial channel covariance matrix (CCM) estimation for intelligent reflecting surface (IRS)-assisted millimeter wave (mmWave) communication systems. Spat…
Beam Training and Alignment for RIS-Assisted Millimeter Wave Systems:State of the Art and Beyond
Peilan Wang, Jun Fang, Weizheng Zhang +3
Reconfigurable intelligent surface (RIS) has recently emerged as a promising paradigm for future cellular networks. Specifically, due to its capability in reshaping the propagation…
Outlier-Detection Based Robust Information Fusion for Networked Systems
Hongwei Wang, Hongbin Li, Wei Zhang +3
We consider state estimation for networked systems where measurements from sensor nodes are contaminated by outliers. A new hierarchical measurement model is formulated for outlier…
Maximum Correntropy Derivative-Free Robust Kalman Filter and Smoother
Hongwei Wang, Hongbin Li, Junyi Zuo +2
We consider the problem of robust estimation involving filtering and smoothing for nonlinear state space models which are disturbed by heavy-tailed impulsive noises. To deal with h…
