Abstract: In this paper, we investigate low-complexity data detection scheme for massive multiple-input multiple-output (MIMO) uplink transmission. We propose to utilize the stair matrix, instead of ...

Abstract: Optimizing wireless propagation channels is essential for advancing future communication technologies, particularly in dynamic vehicular environments where high vehicle mobility is a ...
Differential equations often give rise to rank-structured matrices characterized by low-rank off-diagonal blocks. These matrices can be conveniently represented in a hierarchical format, enabling ...
One scene reflects the themes — A.I., fake news, transgender lives and Gen X — that make the film a classic. By Alissa Wilkinson Neo, the hero of “The Matrix,” is sure he lives in 1999. He has a green ...
Introduction: Donepezil enhances the function of cholinergic nerves by increasing the concentration of acetylcholine, thereby improving clinical symptoms in patients with Alzheimer’s disease (AD).
This paper proposes a novel shrinkage estimator for high-dimensional covariance matrices by extending the Oracle Approximating Shrinkage (OAS) of Chen et al. (2009) to target the diagonal elements of ...
The Hierarchical Computations on Manycore Architectures (HiCMA) library aims to redesign existing dense linear algebra libraries to exploit the data sparsity of the matrix operator. Data sparse ...
