Compressive Sensing for Millimeter Wave Antenna Array Diagnosis
Mohammed E. Eltayeb, Tareq Y. Al-Naffouri, Robert W. Heath
The radiation pattern of an antenna array depends on the excitation weights and the geometry of the array. Due to wind and atmospheric conditions, outdoor millimeter wave antenna e…
Handover Management in 5G and Beyond: A Topology Aware Skipping Approach
Rabe Arshad, Hesham ElSawy, Sameh Sorour +2
Network densification is found to be a potential solution to meet 5G capacity standards. Network densification offers more capacity by shrinking base stations' (BSs) footprints, th…
Robust Regularized Least-Squares Beamforming Approach to Signal Estimation
Mohamed Suliman, Tarig Ballal, Tareq Y. Al-Naffouri
In this paper, we address the problem of robust adaptive beamforming of signals received by a linear array. The challenge associated with the beamforming problem is twofold. Firstl…
Perturbation-Based Regularization for Signal Estimation in Linear Discrete Ill-posed Problems
Mohamed Suliman, Tarig Ballal, Tareq Y. Al-Naffouri
Estimating the values of unknown parameters from corrupted measured data faces a lot of challenges in ill-posed problems. In such problems, many fundamental estimation methods fail…
Distributed Hybrid Scheduling in Multi-Cloud Networks using Conflict Graphs
Ahmed Douik, Hayssam Dahrouj, Tareq Y. Al-Naffouri +1
