Row/Column-First: A Path-based Multicast Algorithm for 2D Mesh-based Network on Chips

open access: yesIranian Journal of Electrical and Electronic Engineering, 2018
In this paper, we propose a new path-based multicast algorithm that is called Row/Column-First algorithm. The proposed algorithm constructs a set of multicast paths to deliver a multicast message to all multicast destination nodes.

Generalized Multicast Multibeam Precoding for Satellite Communications [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2017
This paper deals with the problem of precoding in multibeam satellite systems. In contrast to general multiuser multiple-input-multiple-output (MIMO) cellular schemes, multibeam satellite architectures suffer from different challenges. First, satellite communications standards embed more than one user in each frame in order to increase the channel ...

Orbital Angular Momentum Holography Using Neural Network and Camera in the Loop

open access: yesLaser &Photonics Reviews, Volume 19, Issue 19, October 7, 2025.
Neural network and optimization‐based approaches are introduced for Orbital Angular Momentum (OAM) multiplexed holography, enabling high‐capacity, phase‐only image reconstruction. A Camera‐In‐The‐Loop (CITL) system learns a realistic propagation model to correct system imperfections.
