Abstract

TorchSig uses machine learning (ML) to detect
and classify digitized radio frequency (RF)
signals. Recent updates and improvements to
TorchSig are given, as well as novel features
for image-only spectrogram generation and training,
reducing memory and computational burdens
and making training much faster. A new
GNU Radio out-of-tree (OOT) block is provided
which uses a TorchSig ML model for detecting
signals in real-time.
