Modelo de decisión del espectro para radio cognitiva que integra las pérdidas de propagación en la banda GSM del espectro radioeléctrico

Abstract

This research thesis is framed within the cognitive radio technology, specifically in the spectrum decision step from the cognitive cycle, where is selected the most suitable band for transmission, based on the information gathered during the step before of detecting the spectrum and the requirements of non-licensed users, then the decision model was developed through multiple-criteria decision analysis. Within this development were made measurements at three points in Bogota for a total of thirteen days. The main result was a decision model that integrates propagation loss within its decision parameters, in the GSM band and allows us to use the spectrum an 26% more efficiently.
