Spectrum Sensing Techniques in Cognitive Radio Cycle
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2014, Vol 9, Issue 1
Abstract
The Spectrum sensing techniques in cognitive Radio is presented in this paper. There are three Spectrum sensing techniques of cognitive radio such as cooperative, non-cooperative and interference based detection. Cooperative and non-cooperative techniques are nothing but transmitter detection and receiver detection respectively.Non-cooperative spectrum sensing techniques is classified in three techniques like energy detection, matched filter detection and cyclostationary feature detection. Due to rapid researches in wireless communication and broader application of these wireless networks in the world, efficient utilization of the spectrum has been a persuasive issue for researchers. The development of an intelligent network that can adapt to varying channel conditions by analyzing available spectrum frequency band and increasing the efficiency of an otherwise underutilized spectrum. This paper focuses on the spectrum sensing techniques of the Cognitive Radio in order to detect and utilize empty spaces in the spectrum without creating interference to the primary user. The issue of spectrum underutilization in wireless communication can be solved using Cognitive Radio (CR) technology.
