Optimal Receive Filter Design for Misaligned Over-the-Air Computation
Henrik Hellström, Saeed Razavikia, Viktoria Fodor +1
Over-the-air computation (OAC) is a promising wireless communication method for aggregating data from many devices in dense wireless networks. The fundamental idea of OAC is to exp…
Blind Asynchronous Goal-Oriented Detection for Massive Connectivity
Sajad Daei, Saeed Razavikia, Marios Kountouris +3
Resource allocation and multiple access schemes are instrumental for the success of communication networks, which facilitate seamless wireless connectivity among a growing populati…
Computing Functions Over-the-Air Using Digital Modulations
Saeed Razavikia, Jose Mairton Barros da Silva, Carlo Fischione
Over-the-air computation (AirComp) is a known technique in which wireless devices transmit values by analog amplitude modulation so that a function of these values is computed over…
EVM Mitigation with PAPR and ACLR Constraints in Large-Scale MIMO-OFDM Using TOP-ADMM
Shashi Kant, Mats Bengtsson, Gabor Fodor +2
Although signal distortion-based peak-to-average power ratio (PAPR) reduction is a feasible candidate for orthogonal frequency division multiplexing (OFDM) to meet standard/regulat…
Over-the-Air Federated Learning with Retransmissions (Extended Version)
Henrik Hellström, Viktoria Fodor, Carlo Fischione
Motivated by increasing computational capabilities of wireless devices, as well as unprecedented levels of user- and device-generated data, new distributed machine learning (ML) me…
Simultaneous Wireless Information and Power Transfer for Federated Learning
José Mairton B. da Silva, Konstantinos Ntougias, Ioannis Krikidis +2
In the Internet of Things, learning is one of most prominent tasks. In this paper, we consider an Internet of Things scenario where federated learning is used with simultaneous tra…
