Universal Approximation with XL MIMO Systems: OTA Classification via Trainable Analog Combining

2025 · arXiv (Cornell University)

In this paper, we show that an eXtremely Large (XL) Multiple-Input Multiple-Output (MIMO) wireless system with appropriate analog combining components exhibits the properties of a universal function approximator, similar to a feedforward neural network. By …
