Spectrum sensing and Spectrum shifting implementation in a Cognitive Radio based IEEE 802.22 Wireless Regional Area Network
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 5
Abstract
With the technological advancement in wireless applications more effective and efficient utilization of the available spectrum became the urgent requirement. According to the IEEE 802.22 standard the unlicensed secondary devices can operate in the licensed TV band, because this is the high underutilized licensed band, so long they do not interfere the licensed primary users. Therefore the secondary users having cognitive radio features will automatically switch to another channel or mode upon detecting the primary user in its operating band. In this paper we have presented our work based on spectrum sensing using energy detection and spectrum sifting by using a control index generated as result of sensing the spectrum when the primary user is looking for its licensed band. The simulation shows that the proposed spectrum sensing and spectrum shifting using the control index are easier and guarantee better performance.
