Efficient Spatial Channel Estimation in Extremely Large Antenna Array Communication Systems: A Subspace Approximated Matrix Completion Approach
Published 2025-01-01“…However, its computational complexity is cubic in the number of antennas, which is non-scalable for extremely large-scale antenna array (ELAA) communication systems. To address this issue, in this paper the ELAA channel matrix completion is reformulated as a proximal gradient descent (PGD) problem, where the subgradient of the nuclear norm is computed by singular value thresholding (SVT) operator and the proximal gradient of the <inline-formula> <tex-math notation="LaTeX">$L_{1}$ </tex-math></inline-formula> norm is derived using a softthresholding operator. …”
