Abstract
The analysis of spectrum usage and signal identification, using cognitive radio, was done to identify frequencies that are vacant and is in use in Delta State, Nigeria. A simulink model was designed to analyze a specific frequency spectrum in Delta State, checking if all the frequency stations that range from 87.5-108 MHz are presently being used in Delta State, Nigeria. From the results, it was noticed that by using Software Defined Radio/Simulink, we were able to identify vacant frequencies in the range of frequency under consideration and it was recorded that there are 14 used FM station in Delta State, having 86% underutilized FM Station. Also, the simulink was able to validate the NCC radio station in Delta State, Nigeria.
