New Types of Air Interface Based on Filter Banks for Spectrum Sharing and Coexistence
2015
Today, we witness a continuous evolution of applications for wireless communications. In fact, there is a growing interest in the design and the development of cognitive radio technology to overcome the problem of spectrum scarcity resulting from conventional static spectrum allocation. The concept of cognitive radio is based on opportunistic access to the available frequency resources. It offers to future communication systems the ability to dynamically and locally adapt their operating spectrum by selecting it from a wide range of possible frequencies.
