Implementation of the multichannel DAA-OFDM waveform, the DADS waveform and GNU Radio waveforms. The CR nodes are able to switch from one waveform to another waveform while maintaining communication when the throughput drops under a predifined threshold. The BER feature is also added to the software, along with the possibility to have FDD or TDD for all waveforms.
New version of CogWave that includes spectrum and constellation features.
CogWave is a free and open-source software platform aiming at developing cognitive radio waveforms. The CogWave application allows the exchange of video, audio and text between two USRPs through a graphical user interface (GUI) developed in Qt4/Gstreamer and cognitive radio waveforms developed in IT++. The USRP hardware driver (UHD) C++ application programming interface (API) allows to receive and transmit IQ samples. Combining CogWave with USRP gives a rapid prototyping platform for physical layer design and algorithm validation through a real-time video, audio and text transmission.
