Abstract

The developing demand of wireless applications has increased a lot of constraints on utilization of available radio spectrum. Therefore for efficient utilization of spectrum, we need to sniff the spectrum to determine whether it is being used by primary user or not. Cognitive radio (CR) enables dynamic spectrum access. The biggest challenge related to spectrum sensing is in developing sensing techniques which are able to detect very weak primary user signals while being sufficiently fast and low cost to implement. Spectrum sensing helps to detect the underutilized bands of the spectrum which provides high spectral resolution capability. In this paper various spectrum sensing techniques and their performance analysis is presented.
