Abstract

Cognitive Radio (CR) is a technology which improves the spectrum utilization which some frequency bands is unoccupied or temporary vacate by the users. It is designed to detect communication opportunities in wireless system and to be aware of and sensitive to the changes in its surroundings. However, hidden node has become one of the major problems in cognitive network. Thus, the spectrum sensing is designed to operate cooperatively. If a number of CRs from several locations are sensing the spectrum, they can share the information before making the decision to use the spectrum. This thesis proposes energy detection method on Centralized Cooperative Spectrum Sensing (CCSS) based for simulation and data measurement analysis by including Rayleigh fading channel and Additive White Gaussian Noise (AWGN) into the simulation. Results show cooperative spectrum sensing enhance the detection probability and improve the performance of spectrum sensing.
