Description

The Signal Metadata Format (SigMF) specifies a way to describe sets of recorded digital signals with metadata written in JSON. It was designed for RF recordings, which consist of IQ samples. SigMF can be used to describe general information about the RF recording, the characteristics of the system that generated the samples, and features of the signal itself. This workshop, hosted by two of the SigMF leads (Jacob and Marc), is meant to be informational and include discussion with participants. It will include:

• Quick intro to SigMF for new people (Marc)
• Project update, including state of SigMF within GNU Radio (Jacob)
• Short tutorials
  1. Make your IQ into SigMF with notepad, how does SigMF help me (Marc)
  2. I built tooling that processes IQ, how can SigMF help me (Marc, using Inspectrum as a case-study)
  3. Using SigMF within GNU Radio (Jacob)
  4. Creating a new SigMF extension (Jacob)
• Prerecorded demo from Airbus (3 mins)
• Open discussion and questions
