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…
The Computing Channel: How Modulation Programs the Airwaves
Saeed Razavikia, Carlo Fischione
Distributed computing and distributed artificial intelligence require frequent exchanges of intermediate results, although many applications need only an aggregate rather than mess…
Optimal QAM Constellation for Over-the-Air Computation in the Presence of Heavy-Tailed Channel Noise
Saeed Razavikia, Deniz Gündüz, Carlo Fischione
Over-the-air computation (OAC) enables low-latency aggregation over multiple-access channels (MACs) by exploiting the superposition property of the wireless medium to compute funct…
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…
