Information reuse in dynamic spectrum access [PDF]
2013 IEEE 14th International Conference on Information Reuse & Integration (IRI), 2013 Dynamic spectrum access (DSA), where the permission to use slices of radio spectrum is dynamically shifted (in time an in different geographical areas) across various communications services and applications, has been an area of interest from technical and public policy perspectives over the last decade. The underlying belief is that this will increase
