12-17 (December 2018)Abstract
The present work shows the design of an energy detector, which is intended to measure the energy contained in FM radio frequency signals in the city of Loja generating prior information for the possible action of a Cognitive Radio transmission system (RC ) in that band. The computer tool used to achieve the proposed design is MATLAB. For its operation and interaction with the FM electromagnetic environment, previous data derived from the spectral evaluation carried out in preliminary studies executed within the reference city are included. At the end of the work, a view of the behavior of the detector with real signals is obtained, allowing to obtain detailed data that evidences the spectral underutilization in this communication band opening possibilities of spectral optimization through RC.
