DAB reception

This side informs you about a concept of a open source DAB receiver.

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

Existing open DAB/DAB+/T-DMB software receiver

Software Defined DAB Receiver (complete software receiver)

• SDR-J (running on Linux and Windows, using RTL2832 based USB sticks)
• DAB receiver for gnuradio (by Zurich School of Engineering, documentation in German)

Software defined DAB receiver (up to logical layer)

• Gnuradio DAB constellation using gr-dab and USRP
• Gnuradio blocks for DAB reception (developments from Andreas Mueller, ETHZ)
  • Documentation any other information on http://www.0x7.ch/text/#index3h2
• Under construction gnuradio project on DAB+ reception on CGRAN

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