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…
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…
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…
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…
