Abstract: |
The objective of this project is to design and demonstrate the feasibility of
an innovative intelligent spectrum sensing based cognitive radio architecture for
cyberspace operations. Specifically, the novel cognitive radio architecture
combines intelligent spectrum sensing and dynamic waveform adaptation together
to enhance the performance of military communication systems. The intelligent
spectrum sensing not only detects the existence of active RF transmissions in
the band of interest, but also estimates its important RF parameters such as carrier
frequency and symbol rate. A cyclostationary based blind estimator is
used to detect the information of the primary users in the cognitive network,
which helps the adaptive waveform design. Advanced game theoretic approaches
will be utilized to model and solve this joint competitive game in hierarchical
spectrum sharing games including primary users, secondary users, persistent
jammers and asymmetric information structures. In addition to the theoretical
analysis and Matlab based simulation model, we will also deliver a preliminary
RF demonstration of the proposed intelligent spectrum sensing, waveform
adaption, and resource management technologies via software defined radios. |
Benefits: |
This innovative intelligent spectrum sensing and dynamic waveform adaptation
technology can be widely used in various applications, especially the military
applications, such as the military satellite communications infrastructure.
Additionally, this technology can be applied to other wireless communication
systems, both military and commercial, as well. The intelligent spectrum
sensing techniques proposed here will also find applications in cognitive
electronic warfare (EW) |
