krishna, Yendeti Sai and Narayana, V (2013) spectrum sensing schemes for cognitive radio
networks. BTech thesis.
The growing demand of wireless applications has put a lot of constraints on the usage of available radio spectrum which is limited and precious resource. Cognitive radio is a promising technology which provides a novel way to improve utilisation efficiency of available electromagnetic spectrum. Spectrum sensing used to detect the spectrum holes (underutilised bands of the spectrum) providing high spectral resolution capability. In this report, studied of spectrum sensing techniques is presented. The issues and challenges involved in implementation of spectrum sensing technique energy detection are discussed in detail. We implemented matched filter spectrum sensing technique and studied about cyclostationary detection in spectrum sensing .we implemented OFDM in spectrum sensing techniques as OFDM solves many problems in cognitive radio.
