Advances in Energy Detector and a Matched Filter based Spectrum Sensing: A Survey
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 1
Abstract
The electromagnetic spectrum, licensed to use by governments, is a limited natural resource.The concept of cognitive radio networks (CRNs) has evolved in past few decades and recently implemented in some areas of wireless communication, namely IEEE 802.11af, IEEE802.15.4m, ECMA 392 and IEEE 802.22, as a technique to use underutilizedspectrum. The key development areas in CRNs are spectrum sensing and monitoring, spectrum analysis, spectrum mobility and spectrum decision. Research articles have classified Spectrum sensing as narrowband and wideband spectrum sensing. This paper presents the fundamentals of narrowband spectrum sensing and reviews the implementation and challenges associated with energy detector (ED) and a matched filter (MF) based spectrum sensing.
