Fuzzy Logic System for Opportunistic Spectrum Access using Cognitive Radio
Daniel Nesa Kumar · 2013
Opportunistic spectrum access approach is enabled by cognitive radios which are able to sense the unused spectrum and adapt their operating characteristics to the real-time environment. However, a naive spectrum access for secondary users can make spectrum utilization inefficient and increase interference to adjacent users. In this paper, we propose a novel approach using Fuzzy Logic System (FLS) to control the spectrum access and spectrum for secondary user is selected by possibility of the spectrum access instead of considering the antecedents.
