Energy Detection Based Spectrum Sensing for Cognitive Radio Network
Priyanka Pandya, Aslam Durvesh, Najuk Parekh · 2015
Cognitive radio is an intelligent radio wireless communication technology in order to increase the spectrum efficiency. In this paper one of the most important cognitive radio task i.e. spectrum sensing is explained in detail. Spectrum sensing used to detect the presence of the primary users in a licensed spectrum, which is a fundamental problem for cognitive radio. Increasing efficiency of the spectrum usage is an urgent due to increasing demand for higher data rates, better quality of services and higher capacity. In this paper Energy Detection Technique is discussed in detail.
