SigID Wiki Database

GitHub Release GitHub Downloads (all assets, all releases) GitHub Release Date

Artemis serves as a valuable resource for both personal signal collection and leveraging a vast repository of pre-identified signals. This software application allows users to curate their own collections, but its true strength lies in its integration with a comprehensive database of known signals. This database is directly sourced from the Signal Identification Wiki, an open-source resource collaboratively maintained by a global community of radio enthusiasts.

Database Revision

For quality control purposes, the database undergoes a rigorous review process before integration into Artemis. This review adheres to established guidelines, ensuring the accuracy and completeness of the information presented to users. The specifics of this review process are outlined in the following section.


A good practise (reported also on ) is to write the primary type of modulation (if known) and not all the possible variants. A practical example is reported on Signal Identification Wiki: there is no need to write 8-PSK or QPSK, PSK is enough. The Artemis SigID database is provided without any modulation variants included. The recognized modulations are listed below:


  • AM: Amplitude Modulation
  • FM: Frequency Modulation
  • PM: Phase Modulation
  • LSB: Lower Sideband
  • USB: Upper Sideband
  • VSB: Vestigial Sideband
  • CW: Continuous Wave


  • QAM: Quadrature Amplitude Modulation
  • PSK: Phase-Shift Keying
  • FSK: Frequency-Shift Keying
  • ASK: Amplitude-Shift Keying
  • MSK: Minimum-Shift Keying
  • IFK: Incremental Frequency Keying
  • OOK: On-Off Keying
  • FDM: Frequency-Division Multiplexing
  • BOC: Binary Offset Carrier Modulation
  • CDMA: Code Division Multiple Access
  • TDMA: Time Division Multiple Access
  • FBMC: Filter Bank Multi Carrier
  • UFMC: Universal Filtered Multi Carrier
  • PCM: Pulse Code Modulation
  • PPM: Pulse Position Modulation
  • FMCW: Frequency-Modulated Continuous Wave
  • Pulse: Pulse

Spread Spectrum

  • CSS: Chirp Spread Spectrum
  • DSSS: Direct Sequence Spread Spectrum
  • FHSS: Frequency Hopping Spread Spectrum
  • THSS: Time Hopping Spread Spectrum


Locations are either countries or special token (Worldwide, Europe, etc.) . Precise location of the TX station, towns and cities are converted to their respective countries.
