Deep Wireless Neural Network Uses MIMO Relays and Power Amplifiers

Researchers have developed a novel deep wireless physical neural network (WPNN) that embeds computation directly into analog hardware, aiming for lower energy consumption and latency. This WPNN utilizes a multi-hop MIMO relay network where power amplifiers act as activation functions, enabling end-to-end training of the network's parameters. Two transceiver designs were proposed based on channel state information availability, and simulations demonstrated accurate over-the-air image classification, highlighting the benefits of hardware nonlinearity for enhanced inference.
