liquid-dsp is a free and open-source digital signal processing (DSP) library designed specifically for software-defined radios on embedded platforms. The aim is to provide a lightweight DSP library that does not rely on a myriad of external dependencies or proprietary and otherwise cumbersome frameworks.
liquid-usrp contains simple applications for communicating over the air using the universal software radio peripheral (USRP). Furthermore, a simple packet radio interface is presented that allows the user to transmit data packets of any length, modulation scheme, and forward error-correction scheme desired.
For more information on the USRP itself, refer to http://www.ettus.com/.
