Suscan - A realtime DSP library

Important note: if you are looking for the graphical application based on this library, it has been deprecated and removed from the source tree. Suscan (GUI) was a GTK3-based application with poor performance and responsiveness that was eventually replaced by the Qt5 application SigDigger. You will still need Suscan (library) in order to compile SigDigger.

Suscan is a realtime DSP processing library. It provides a set of useful abstractions to perform dynamic digital signal analysis and demodulation. Suscan offers features like:

• Multicore-friendly signal processing, based on worker threads
• Generic ASK, FSK, PSK and audio demodulators
• An extensible codec interface
• Configuration file API (XML)
• Source API based on SoapySDR

Getting the code

Just clone it from the GitHub repository. Make sure you pass --recurse-submodules to git clone so all required submodules are also cloned.

% git clone --recurse-submodules https://github.com/BatchDrake/suscan.git

Building and installing Suscan

In order to build Suscan, you will need the development files for the following packages:

• sigutils
• fftw3
• sndfile
• SoapySDR
• libxml-2.0

If you are in a Debian-like operating system, you will also need cmake and build-essential.

After installing all dependencies, enter Suscan's source directory and compile by typing:

% cd suscan
% mkdir build
% cd build
% cmake ..
% make

If the previous commands were successful, you are ready to install Suscan in your system by executing (as root):

# make install

You can verify your installation by running:

% suscan.status

If everything went fine, you should see the message:

suscan.status: suscan library loaded successfully.
