The objective of this project was to conduct fundamental research that will lead to the development of cognitive communications protocols for satellite and space communications with possible broad applications in defense, homeland-security as well as consumer telecommunications. Such cognitive communications protocols are to be implemented on wideband autonomous cognitive radios WACRs that will have the ability to sense state of the radiofrequency RF spectrum and the network and self-optimize their operating modes in response to this sensed state. The project developed three types of cognitive communications protocols a machine learning aided cognitive anti-jamming and interference avoidance communications protocols, b cognitive cooperative beamforming, and c cognitive multi-mode communications protocols. Together, the advances made in this project form a foundation for achieving effective spectrum coexistence, interoperability and improved reliability in satellite transceivers in the presence of both inadvertent interference and deliberate jammers. Given the demonstrated promise, it is recommended that further research be pursued to advance the proposed WACR as the basis for future space communication systems that will offer significant benefits to national warfighting and peacekeeping capabilities.
