Abstract

The objective of this project is to design and demonstrate the feasibility ofan innovative intelligent spectrum sensing based cognitive radio architecture forcyberspace operations. Specifically, the novel cognitive radio architecturecombines intelligent spectrum sensing and dynamic waveform adaptation togetherto enhance the performance of military communication systems. The intelligentspectrum sensing not only detects the existence of active RF transmissions inthe band of interest, but also estimates its important RF parameters such as carrierfrequency and symbol rate. A cyclostationary based blind estimator isused to detect the information of the primary users in the cognitive network,which helps the adaptive waveform design. Advanced game theoretic approacheswill be utilized to model and solve this joint competitive game in hierarchicalspectrum sharing games including primary users, secondary users, persistentjammers and asymmetric information structures. In addition to the theoreticalanalysis and Matlab based simulation model, we will also deliver a preliminaryRF demonstration of the proposed intelligent spectrum sensing, waveformadaption, and resource management technologies via software defined radios.
