Missing value imputation in a data matrix using the regularised singular value decomposition

MethodsX, 2023
Some statistical analysis techniques may require complete data matrices, but a frequent problem in the construction of databases is the incomplete collection of information for different reasons. One option to tackle the problem is to estimate and impute

Hybrid Precoding for Massive mmWave MIMO Systems

IEEE Access, 2019
Due to high costs and power consumptions, fully digital baseband precoding schemes are usually prohibitive in millimeter-wave massive MIMO systems. Therefore, hybrid precoding strategies become promising solutions.
