Spectrum Prediction Technique in Cognitive Radio Over Different Fading Channels
Journal Title: International Journal of Electrical, Electronics and Mechanical Fundamentals (www.ijeemf.com) - Year 2012, Vol 2, Issue 1
Abstract
Wireless communication importance is that it is increasing throughout the world due to broadband and cellular technologies. In the world everyone would like to be connected seamlessly anytime anywhere through the network that is best. Laptops with wifi, sensors, Cell phones – all are wireless devices and they use a finite amount of radio spectrum. With the number of devices increased, they compete for limited bandwidth available and service level provided to them is degraded. Also traditional fixed spectrum allocation policy will not meet the needs and services of the wireless users for long time. The result of simulation shows that the mechanism could obviously decrease the interference of detection error to authorized system, and could apparently reduce the cost of frequency spectrum access chances of cognition system caused by detection error.
