Time-varying Wireless Channel Tracking with Online Parameter Learning via the Birth-Death-Drift Model
Tiancheng Gao, Mohamed Akrout, Faouzi Bellili +1
Accurate massive MIMO channel state information (CSI) acquisition with low pilot overhead is critical in dynamic propagation environments. Exploiting temporal correlation is key to…
Guided Wireless Technology for Near-Field Communication
Mohamed Akrout, Amine Mezghani, Faouzi Bellili +1
Guided wireless technology is an innovative approach that combines the strengths of guided waves and wireless communication. In traditional wireless systems, signals propagate thro…
Capacity Based Design of Slot Array Antennas
Volodymyr Shyianov, Bamelak Tadele, Vladimir I. Okhmatovski +2
Historically, the design of antenna arrays has evolved separately from Shannon theory. Shannon theory adopts a probabilistic approach in the design of communication systems, while…
Unlabeled Compressed Sensing from Multiple Measurement Vectors
Mohamed Akrout, Amine Mezghani, Faouzi Bellili
This paper introduces an algorithmic solution to a broader class of unlabeled sensing problems with multiple measurement vectors (MMV). The goal is to recover an unknown structured…
Lens-Type Redirective Intelligent Surfaces for Multi-User MIMO Communication
Bamelak Tadele, Faouzi Bellili, Amine Mezghani +2
This paper explores the idea of using redirective reconfigurable intelligent surfaces (RedRIS) to overcome many of the challenges associated with the conventional reflective RIS. W…
Next-slot OFDM-CSI Prediction: Multi-head Self-attention or State Space Model?
Mohamed Akrout, Faouzi Bellili, Amine Mezghani +1
The ongoing fifth-generation (5G) standardization is exploring the use of deep learning (DL) methods to enhance the new radio (NR) interface. Both in academia and industry, researc…
