Mathematical Theory of Atomic Norm Denoising In Blind Two-Dimensional Super-Resolution (Extended Version)
Mohamed A. Suliman, Wei Dai
This paper develops a new mathematical framework for denoising in blind two-dimensional (2D) super-resolution upon using the atomic norm. The framework denoises a signal that consi…
Blind Two-Dimensional Super-Resolution and Its Performance Guarantee (Extended Version)
Mohamed A. Suliman, Wei Dai
We study the problem of identifying the parameters of a linear system from its response to multiple unknown waveforms. We assume that the system response is a scaled superposition…
SNR Estimation in Linear Systems with Gaussian Matrices
Mohamed A. Suliman, Ayed M. Alrashdi, Tarig Ballal +1
This paper proposes a highly accurate algorithm to estimate the signal-to-noise ratio (SNR) for a linear system from a single realization of the received signal. We assume that the…
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…
Supplementary Appendix for: Constrained Perturbation Regularization Approach for Signal Estimation Using Random Matrix Theory
Mohamed Suliman, Tarig Ballal, Abla Kammoun +1
In this supplementary appendix we provide proofs and additional extensive simulations that complement the analysis of the main paper (constrained perturbation regularization approa…
