Learning radio signals using radio signal transformers

A system to process one or more radio signals, the system comprising:

• one or more processors;
• and
• one or more computer readable media storing computer code that, when executed by the one or more processors, is configured to perform a plurality of operations, the operations comprising:
• providing a first set of input data representing one or more radio signals to a first neural network that has been trained to generate output data representing an estimation of one or more characteristics of a radio signal;
• obtaining first output data generated by the first neural network based on the first neural network processing the first set of input data;
• receiving, by a signal transformer, a second set of input data that includes (i) the first set of input data and (ii) the first output data generated by the first neural network;
• generating, by the signal transformer and based on the second set of input data, data representing a transformed radio signal by applying one or more transforms of a set of predetermined transforms to the first set of input data representing the one or more radio signals;
• providing the data representing the transformed radio signal to a second neural network that has been trained to generate output data describing the one or more radio signals based on processing the data representing the transformed radio signal;
• obtaining second output data generated by the second neural network based on the second neural network processing the data representing the transformed radio signal;
• and
• determining based on the second output data a set of information describing one or more radio signals in the first set of input data.
