GNU radio has all the bits to do signal processing from raw analog data to symbols to bytes. For example, I can use my SDR to record various signals in my neighborhood, make a guess that it's manchester encoded, then pass that signal to a symbol demodulaor, pass the symbols through a manchester decoder, then on to a protocol decoder (IIRC my tires have batteries and transmitters to send their pressure level to my car). GNU radio has bits for all these steps, but yeah, you kind of need to know the modulation schema and the codec scheme to make sense of it. Here's a nice example: https://bkerler.github.io/OregonDecoder/ https://bkerler.github.io/OregonDecoder/
