Abstract
This final report summarizes the activities of the FoT project Dynamic Telecommunications Solutions (DynamiT). The project has run for three years during the period 2008 - 2010. The purpose of the project has been to conduct research and development in flexible and dynamic solutions for efficient tactical communications. The purpose has also been to evaluate the potential of spectrum flexibility at higher system levels. Dynamic spectrum access (DSA) and cognitive radio (CR) have been focus of the project. The Swedish Armed Forces' needs for spectrum and DSA have been investigated. Novel methods for spectrum sensing based on results from electromagnetic interference classification have been developed and evaluated. Additionally, methods for sensor selection for cooperative spectrum sensing have been developed and evaluated. An architecture for development of software and hardware demonstrators has been developed. The architecture has been used to develop software and hardware demonstrators that have been used to validate and demonstrate the spectrum sensing algorithms. The architecture supports a future development of a complete cognitive radio. A software defined radio (SDR) is flexible and reconfigurable but also sensitive to IT threats. IT-security issues have been investigated and an IT-security architecture based on virtual machines is proposed. The project has established knowledge in several aspects of flexible and dynamic telecommunications. The results and knowledge will allow FOI to support the Swedish Armed Forces in the areas of dynamic spectrum access and cognitive radio, and to provide requirements and procurement support.
