Energy Efficient Design of Active STAR-RIS-Aided SWIPT Systems
Sajad Faramarzi, Hosein Zarini, Sepideh Javadi +4
In this paper, we consider the downlink transmission of a multi-antenna base station (BS) supported by an active simultaneously transmitting and reconfigurable intelligent surface…
Meta Reinforcement Learning for Resource Allocation in Aerial Active-RIS-assisted Networks with Rate-Splitting Multiple Access
Sajad Faramarzi, Sepideh Javadi, Farshad Zeinali +5
Mounting a reconfigurable intelligent surface (RIS) on an unmanned aerial vehicle (UAV) holds promise for improving traditional terrestrial network performance. Unlike conventional…
Matrix Completion via Nonsmooth Regularization of Fully Connected Neural Networks
Sajad Faramarzi, Farzan Haddadi, Sajjad Amini +2
Conventional matrix completion methods approximate the missing values by assuming the matrix to be low-rank, which leads to a linear approximation of missing values. It has been sh…
SLIPT in Joint Dimming Multi-LED OWC Systems with Rate Splitting Multiple Access
Sepideh Javadi, Sajad Faramarzi, Farshad Zeinali +5
Optical wireless communication (OWC) systems with multiple light-emitting diodes (LEDs) have recently been explored to support energy-limited devices via simultaneous lightwave inf…
