RAIN-FIT: Learning of Fitting Surfaces and Noise Distribution from Large Data Sets
Omar M. Sleem, Sahand Kiani, Constantino M. Lagoa
This paper proposes a method for estimating a surface that contains a given set of points from noisy measurements. More precisely, by assuming that the surface is described by the…
Unsupervised Learning for Pilot-free Transmission in 3GPP MIMO Systems
Omar M. Sleem, Mohamed Salah Ibrahim, Akshay Malhotra +2
Reference signals overhead reduction has recently evolved as an effective solution for improving the system spectral efficiency. This paper introduces a new downlink data structure…
Parsimonious System Identification from Fragmented Quantized Measurements
Omar M. Sleem, Constantino M. Lagoa
Quantization is the process of mapping an input signal from an infinite continuous set to a countable set with a finite number of elements. It is a non-linear irreversible process,…
Lp Quasi-norm Minimization: Algorithm and Applications
Omar M. Sleem, M. E. Ashour, N. S. Aybat +1
Sparsity finds applications in areas as diverse as statistics, machine learning, and signal processing. Computations over sparse structures are less complex compared to their dense…
