Adaptive Passive Beamforming in RIS-Aided Communications With Q-Learning
Thomas Chêne, Oumaïma Bounhar, Ghaya Rekaya-Ben Othman +1
Reconfigurable Intelligent Surfaces (RIS) appear as a promising solution to combat wireless channel fading and interferences. However, the elements of the RIS need to be properly o…
Revisited Design Criteria For STBCs With Reduced Complexity ML Decoding
Asma Mejri, Mohamed-Achraf Khsiba, Ghaya Rekaya-Ben Othmane
The design of linear STBCs offering a low-complexity ML decoding using the well known Sphere Decoder (SD) has been extensively studied in last years. The first considered approach…
Macro and Micro Diversity Behaviors of Practical Dynamic Decode and Forward Relaying schemes
Mélanie Plainchault, Nicolas Gresset, Ghaya Rekaya Ben-Othman
In this paper, we propose a practical implementation of the Dynamic Decode and Forward (DDF) protocol based on rateless codes and HARQ. We define the macro diversity order of a tra…
Construction of New Delay-Tolerant Space-Time Codes
Mireille Sarkiss, Ghaya Rekaya-Ben Othman, Mohamed Oussama Damen +1
Perfect Space-Time Codes (STC) are optimal codes in their original construction for Multiple Input Multiple Output (MIMO) systems. Based on Cyclic Division Algebras (CDA), they are…
Augmented Lattice Reduction for MIMO decoding
Laura Luzzi, Ghaya Rekaya-Ben Othman, Jean-Claude Belfiore
Lattice reduction algorithms, such as the LLL algorithm, have been proposed as preprocessing tools in order to enhance the performance of suboptimal receivers in MIMO communication…
Hard and Soft Spherical-Bound Stack decoder for MIMO systems
Rym Ouertani, Ghaya Rekaya Ben-Othman, Abdellatif Salah
Classical ML decoders of MIMO systems like the sphere decoder, the Schnorr-Euchner algorithm, the Fano and the stack decoders suffer of high complexity for high number of antennas…
