TAILIEUCHUNG - Advance in Cognitive Radio Systems

In the latest years much research effort was devoted to envision a new paradigm for wireless transmission. Results from recent works (Wireless Word Research Forum, 2005) indicate that a possible solution would lie in utilizing in a more efficient manner the diverse Radio Access Technologies1 (RATs) that are available nowadays, with the purpose of enabling interoperability among them and convergence into one global telecom infrastructure (beyond 3G). Turning such a representation into reality requires endowing both the network and the user terminal with advanced management functionalities to ensure an effective utilization of radio resources. From the network providers’ side, this. | ADVANCES IN ADVANCES IN COGNITIVE RADIO SYSTEMS Edited by Cheng-Xiang Wang and Joseph Mitola III Advances in Cognitive Radio Systems Edited by Cheng-Xiang Wang and Joseph Mitola III Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2012 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
