Orthogonal Space-Time Block Code Based Over-the-Air Computation in Backscatter Sensor Networks

J Wang, Y Li, M Jiang, Q Zhang - IEEE Communications Letters, 2024 - ieeexplore.ieee.org
In backscatter sensor networks, performing over-the-air computation (AirComp) is
challenging, because backscatter devices are impossible to accomplish channel estimation …
