Software Defined DAB Receiver (complete software receiver)

  • Qt-DAB (running on Linux and Windows, using RTL2832 based USB dongles)
  • welle.io (running on Linux and Windows, using RTL2832 based USB dongles and airspy dongles)
  • DAB receiver for gnuradio (by Zurich School of Engineering, documentation in German)

Software defined DAB receiver (from logical layer up to application layer)

Openmokast

Open Receiver project from CRC using RDI streams from DAB baseband receivers/decoders.

Receiver for the Psion Wavefinder


Open source DAB receiver (concept)

Goal

To develop libraries to cover all parts of a full DAB and DAB+ SDR receiver.

  • Well defined library APIs
  • Easy to use APIs
  • Cross platform support (x86, arm, Linux, Windows, etc.)


Requirements

  • Based on the SDR-J code
  • Use of C++11 to use the threading feature
  • Multicore support
  • cmake as build environment


Architecture

Library Name Purpose
libsdrsource

Interface to different SDR devices

libdabdemod
  • OFDM demodulation
  • Frequency synchronization
  • Time synchronization
  • Output of the digital DAB stream
libdabdecode
  • DAB and DAB+ frame decoding (FIC, Superframes etc.)
  • CRC correction
  • Output of MPEG or ACC stream
End user program
  • Place holder for GUIs
  • There can be a QT GUI, a GTK GUI or a Kodi plugin

API description

  • TBD


To be discussed

  • Naming of libraries
  • APIs


GUI Wishlist

  • Easy to use
  • Channel scan
  • High DPI support
  • libnotify support
