Abstract
A system can receive respective data from respective sensors, wherein the respective data represents respective gradient values for a neural network produced by the respective first sensors according to a federated learning process. The system can transform the respective data into respective analog waveforms. The system can apply orthogonal frequency-division multiplexing to the respective analog waveforms to produce respective aligned analog waveforms. The system can create a superposition analog waveform that comprises a superposition of the respective aligned analog waveforms. The system can transmit the superposition analog waveform to an access point, wherein the access point is configured to update the neural network with the superposition analog waveform according to the federated learning process.
