Description

The objective of this project is to design and demonstrate the feasibility of<br>an innovative intelligent spectrum sensing based cognitive radio architecture for<br>cyberspace operations. Specifically, the novel cognitive radio architecture<br>combines intelligent spectrum sensing and dynamic waveform adaptation together<br>to enhance the performance of military communication systems. The intelligent<br>spectrum sensing not only detects the existence of active RF transmissions in<br>the band of interest, but also estimates its important RF parameters such as carrier<br>frequency and symbol rate. A cyclostationary based blind estimator is<br>used to detect the information of the primary users in the cognitive network,<br>which helps the adaptive waveform design. Advanced game theoretic approaches<br>will be utilized to model and solve this joint competitive game in hierarchical<br>spectrum sharing games including primary users, secondary users, persistent<br>jammers and asymmetric information structures. In addition to the theoretical<br>analysis and Matlab based simulation model, we will also deliver a preliminary<br>RF demonstration of the proposed intelligent spectrum sensing, waveform<br>adaption, and resource management technologies via software defined radios.
