Over-the-Air Aggregation for Federated Learning: Waveform Superposition and Prototype Validation

Huayan Guo, Yifan Zhu, Haoyu Ma +5

In this paper, we develop an orthogonal-frequency-division-multiplexing (OFDM)-based over-the-air (OTA) aggregation solution for wireless federated learning (FL). In particular, th…
