Interference Cancellation for OTFS-Based Over-the-Air Computation
Xinyu Huang, Henrik Hellstrom, Carlo Fischione
This paper investigates over-the-air computation (AirComp) in the context of multiple-access time-varying multipath channels. We focus on a scenario where devices with high mobilit…

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…
