Software Defined Radio Architectures
CMSF-SI has been researching Software Defined Radio (SDR) and Cognitive Radio (CR) technologies for the commercial and public safety sectors. CMSF-SI believes Reconfigurable Radio Systems (RRS) would be the drivers for the next step in the evolution of wireless communications. These technologies are seen by us as an enabler for the introduction of new users and applications in co-existence with incumbent uses in some frequency bands, such as, for example, TV White Spaces in the UHF band.
Even though there currently are substantial uncertainties relating to spectrum regulation and to the attractiveness for different stakeholders of associated business models, CMSF-SI intends to be at the forefront of experimentation with RRS technologies in the area of pre-commercial and commercial applications. In a commitment towards the reseach community from who we have benefit so much, the majority of our software packages are released under GNU General Public License (GPL) v3 , meaning the research community will have the freedom to run, copy, distribute, study, change and improve our software.
