# 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
|
|
```
