Near-Field Channel Estimation For XL-MIMO Systems Using Variational Bayesian Learning
JN Pisharody, A Rajoriya… - IEEE Transactions on …, 2024 - ieeexplore.ieee.org
We estimate the uplink channel of an extra large-scale multiple-input-multiple-output (XL-
MIMO) system, with the base station (BS) consisting of multiple antenna sub-arrays. The BS …
