A Survey on Spectrum Sensing Techniques for Cognitive Radio Networks
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2015, Vol 2, Issue 2
Abstract
Cognitive Radio has derived the attention of researchers for the simple reason of optimum utilization of available spectrum of wireless communication in the recent scenario. The spectrum sensing problem has gained new aspects with cognitive radio and opportunistic spectrum access concepts. It is one of the most challenging issues in cognitive radio systems. In this paper, a survey of spectrum sensing methodologies for cognitive radio is presented. Various aspects of spectrum sensing problem are studied from a cognitive radio perspective and challenges associated with spectrum sensing are given and enabling spectrum sensing methods are reviewed and most common spectrum sensing techniques in the cognitive radio literature are explained
