An Analysis of Spectrum Sensing Techniques for Cognitive Radio
Authors(2) :-Mallikarjun Dheshmuk, Arun Badiger
Spectrum is a very scarce and precious resource for a communication system. The entire spectrum will not be used all the time. Some part of the spectrum always remains unused. Also, the television transmission is shifting from analog to digital. Hence, the spectrum which was earlier intended for analog television has been rendered unused. Such unused frequencies are known as white spaces. Conventional systems employ static spectrum allocation, leading to inefficient utilization of spectrum. In order to utilize the spectrum in an efficient manner, spectrum allocation must be done in a dynamic way. Cognitive capability is the ability to sense the communication environment and adapt the parameters accordingly, so as to utilize the spectrum in an effective way. Spectrum sensing is the prime most step of cognitive radio. In this paper, several spectrum sensing techniques like energy based detection, matched filtering, cyclostationary have been analyzed and their simulation results are discussed.
