Optimal QAM Constellation for Over-the-Air Computation in the Presence of Heavy-Tailed Channel Noise

Saeed Razavikia, Deniz Gunduz, Carlo Fischione

ICASSP 2026poster

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 functions efficiently in distributed networks. A critical but often overlooked challenge is that electromagnetic interference…

Two-Snapshot DOA Estimation Via Hankel-Structured Matrix Completion

Mohammad Bokaei, Saeed Razavikia, Arash Amini, Stefano Rini

ICASSP 2022accepted

In this paper, we study the problem of estimating the direction of arrival (DOA) using a sparsely sampled uniform linear array (ULA). Based on an initial incomplete ULA measurements, our strategy is to choose a sparse subset of array elements for measuring the next snapshot. Then, we use a Hankel-st…
