leansdr consists of:
- A simple data-flow framework for signal processing
- A C++ library of software-defined radio functions
- Applications built on top of the above.
Currently the main application is leandvb.
leandvb is a DVB-S demodulator designed for speed rather than sensitivity.
See http://www.pabr.org/radio/leandvb for details and use cases.
