Optimal value of past samples for decision making in cognitive radio networks

Abstract: Contexto: El modelado y predicción del uso del espectro por parte de los PU es un aspecto importante para reducir la interferencia entre los SU y PU, y mejorar el desempeño de la decisión espectral. Lo anterior requiere de información espectral pasada, que permita al algoritmo modelar el comportamiento del PU. Objetivo: Determinar el valor óptimo de muestras pasadas y tiempo de recalculo de criterios de decisión, para los algoritmos de toma de decisiones en redes de radio cognitiva. Metodología: Se… Show more

“…The cumulative number of spectral handovers obtained during the transmission time or ST of the SU is used as a performance metric to analyze the proposed strategy through the five developed modules. This metric is associated with spectral mobility and allows quantifying the channel shift of the SU (Hernandez et al, 2020a(Hernandez et al, , 2020b. A spectral handover in CRN occurs when an SU must change its channel to continue its communication in another spectral opportunity.…”
