Cnn-based demodulating and decoding systems and methods for universal receiver

Abstract

Presented are systems and methods for automatically creating and labeling training data for training-based radio, comprising receiving, at a receiver, a frame that comprises a modulated radio frequency (RF) signal comprising a set of waveforms that correspond to payload data. The payload data comprises a sequence of random bits. In embodiments, until a stopping condition is met one or more steps are performed, comprising detecting the frame; demodulating the modulated RF signal to reconstruct the sequence of random bits; using the reconstructed sequence to determine whether the payload data has been correctly received; in response to determining that the payload data has not been correctly received, discarding it and, otherwise, accepting the sequence of random bits as a training label; associating the training label with the modulated RF signal to generate labeled training data; and appending the labeled training data to a labeled training data set.
