It Takes Two Moments: Rigidity and Limits of Continuous Encoders for Over-the-Air Computation
Saeed Razavikia
We study over-the-air computation of functions, such as empirical variance, formed by combining two separately postprocessed sums of locally transformed observations. We consider c…
Function Computation Over Multiple Access Channels via Hierarchical Constellations
Saeed Razavikia, Mohammad Kazemi, Deniz Gündüz +1
We study function computation over a Gaussian multiple-access channel (MAC), where multiple transmitters aim at computing a function of their values at a common receiver. To this e…
Towards Optimal Constellation Design for Digital Over-the-Air Computation
Saeed Razavikia, Deniz Gündüz, Carlo Fischione
Over-the-air computation (OAC) has emerged as a key technique for efficient function computation over multiple-access channels (MACs) by exploiting the waveform superposition prope…
Timely and Painless Breakups: Off-the-grid Blind Message Recovery and Users' Demixing
Sajad Daei, Saeed Razavikia, Mikael Skoglund +2
In the near future, the Internet of Things will interconnect billions of devices, forming a vast network where users sporadically transmit short messages through multi-path wireles…
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…
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…
