Evaluation of Spectrum Utilization through Cognitive Radio

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. Hence, the analysis can be recommended in larger coverage.
