Abstract
CogWave is an open-source software framework aiming at developing cognitive radio (CR) waveforms. Multiple waveforms have been implemented in CogWave, such as the multichannel DAA-OFDM waveform, the DADS waveform, and GNU Radio waveforms. CogWave provides the means to implement different CR waveforms and to develop rules to switch between different CR waveforms during run-time according to the user needs and the electromagnetic environment. A description of a CR demonstrator is given, in which a jammer perturbs the data transmission between two CR nodes. It is shown that when the throughput drops under a predefined threshold, the CR nodes switch from the DADS to the multichannel DAA-OFDM automatically while maintaining communication.
