Analysis of Cognitive Radio a Way to Increase Spectrum Efficiency Using Periodogram
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 4
Abstract
The topic of spectrum sensing and spectrum allocation has gained a great deal of interest in the context of cognitive radios for dynamic spectrum access networks. Spectrum sensing and allocation is one of the crucial functionalities of a cognitive radio in order to apply the radio environment. Different sensing and allocation techniques serve different purposes based on their advantages and drawbacks. Spectrum sensing is an inherent ability of cognitive radio to autonomously perform required calculations & detects unused spectrum that is spectrum holes in order to increase spectrum efficiency. In this paper various algorithms for spectrum sensing techniques are discussed &analysis of cognitive radio is done using energy detector spectrum sensing which is also called periodogram.
