Amplify-and-Forward Relaying for Hierarchical Over-the-Air Computation

Over-the-air computation (AirComp) has emerged as a promising technique in future intelligent wireless networks, which enables swift functional computation among distributed wireless devices (WDs) by exploiting the superposition property of wireless channels. This paper studies a new hierarchical Ai...
