libsdr - A simple software defined radio (SDR) library

First of all: I assembled this library for my one entertainment and to learn something about software defined radio. If you are interested into a full-featured, performant SDR framework, consider using GNU radio (http://gnuradio.org).

Although being simple, libsdr is sufficient to write a simple SDR receiver application (http://github.com/hmatuschek/sdr-rx, above). This RX application supports several input sources (i.e. sound card, files, RTL2382 dongles etc.) and modes (i.e. AM, FM, SSB, CW, etc.).

Build

The only required run-time dependency of libsdr is libpthread, which is available on all Unix-like OSs like Linux and MacOS X. It is also available for windows if mingw is used (http://www.mingw.org) of compilation. There are also some optional dependencies, which allow for the usage of some additional features of the library.

Qt5 (http://qt-project.org) - Enables the libsdr-gui library implementing some graphical user interface elements like a spectrum view.
fftw3 (http://www.fftw.org) - Also required by the GUI library and allows for FFT-convolution filters.
PortAudio (http://www.portaudio.com) - Allows for sound-card input and output.
librtlsdr (http://rtlsdr.org) - Allows to interface RTL2382U based USB dongles.

For the compilation of the library, cmake (http://www.cmake.org) is also required (as well as a compiler like gcc or clang of cause).

Compiling the library is the canonical cmake path:

mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=RELEASE 
make
