In this paper the design and implementation of the University of Alberta user interface management system (UIMS) is discussed. This UIMS is based on the Seeheim model of user interfaces, which divides the user interface into three separate components. ...

In this paper, we consider underlay cognitive radio systems in which secondary users coexist with users in primary networks whose radio band is licensed. The secondary subnetwork comprising the cognitive users utilizes the cognitive radio technology to ...

Cognitive Radio (CR) is an emerging radio mechanism that dynamically adjusts its radio parameters, so as to utilize the unused spectrum bands (spectrum holes) to overcome the spectrum shortage problem. The wireless devices are increasing enormously and ...
