Precise Error Analysis of the LASSO under Correlated Designs
Ayed M. Alrashdi, Houssem Sifaou, Abla Kammoun +2
In this paper, we consider the problem of recovering a sparse signal from noisy linear measurements using the so called LASSO formulation. We assume a correlated Gaussian design ma…
Asymptotic Performance of Box-RLS Decoders under Imperfect CSI with Optimized Resource Allocation
Ayed M. Alrashdi, Abla Kammoun, Ali H. Muqaibel +1
This paper considers the problem of symbol detection in massive multiple-input multiple-output (MIMO) wireless communication systems. We consider hard-thresholding preceeded by two…
Performance Analysis of Dual-Hop Underwater Wireless Optical Communication Systems over Mixture Exponential-Generalized Gamma Turbulence Channels
Emna Zedini, Abla Kammoun, Hamza Soury +2
In this work, we present a unified framework for the performance analysis of dual-hop underwater wireless optical communication (UWOC) systems with amplify-and-forward fixed gain r…
High-Dimensional Quadratic Discriminant Analysis under Spiked Covariance Model
Houssem Sifaou, Abla Kammoun, Mohamed-Slim Alouini
Quadratic discriminant analysis (QDA) is a widely used classification technique that generalizes the linear discriminant analysis (LDA) classifier to the case of distinct covarianc…
Improved Design of Quadratic Discriminant Analysis Classifier in Unbalanced Settings
Amine Bejaoui, Khalil Elkhalil, Abla Kammoun +2
The use of quadratic discriminant analysis (QDA) or its regularized version (R-QDA) for classification is often not recommended, due to its well-acknowledged high sensitivity to th…
Performance of Multibeam Very High Throughput Satellite Systems Based on FSO Feeder Links with HPA Nonlinearity
Emna Zedini, Abla Kammoun, Mohamed-Slim Alouini
Due to recent advances in laser satellite communications technology, free-space optical (FSO) links are presented as an ideal alternative to the conventional radio frequency (RF) f…
