In once aspect, a system is disclosed that includes a processor and a storage device storing computer code that includes operations. The operations may include obtaining first output data generated by a first neural network based on the first neural network processing a received radio signal, receiving, by a signal transformer, a second set of input data that includes (i) the received radio signal and (ii) the first output data, generating, by the signal transformer, data representing a transformed radio signal by applying one or more transforms to the received radio signal, providing the data representing the transformed radio signal to a second neural network, obtaining second output data generated by the second neural network, and determining based on the second output data a set of information describing the received radio signal.application/pdfenLearning radio signals using radio signal transformersPatenthttp://pimg-fpiw.uspto.gov/fdd/31/968/102/0.pdf15970510G06N3/08G06N3/0454H04B1/0003H04B17/30910296831
