Harmonic Retrieval Using Weighted Lifted-Structure Low-Rank Matrix Completion
Mohammad Bokaei, Saeed Razavikia, Stefano Rini +2
In this paper, we investigate the problem of recovering the frequency components of a mixture of complex sinusoids from a random subset of equally-spaced time-domain sample…
Blind Federated Learning via Over-the-Air q-QAM
Saeed Razavikia, José Mairton Barros Da Silva Júnior, Carlo Fischione
In this work, we investigate federated edge learning over a fading multiple access channel. To alleviate the communication burden between the edge devices and the access point, we…
ChannelComp: A General Method for Computation by Communications
Saeed Razavikia, José Mairton Barros Da Silva Júnior, Carlo Fischione
Over-the-air computation (AirComp) is a well-known technique by which several wireless devices transmit by analog amplitude modulation to achieve a sum of their transmit signals at…
SumComp: Coding for Digital Over-the-Air Computation via the Ring of Integers
Saeed Razavikia, José Mairton Barros Da Silva Júnior, Carlo Fischione
Communication and computation are traditionally treated as separate entities, allowing for individual optimizations. However, many applications focus on local information's functio…
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…
Off-the-grid Blind Deconvolution and Demixing
Saeed Razavikia, Sajad Daei, Mikael Skoglund +2
We consider the problem of gridless blind deconvolution and demixing (GB2D) in scenarios where multiple users communicate messages through multiple unknown channels, and a single b…
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…
