Model Simulation & Resource Allocation in Cognitive Radio System

Amit Yadav, Swati Swati

Abstract


Cognitive radio is the technique where different sorts of wireless communication devices work dynamically and change frequencies and other parameters over time. The idea of cognitive radio (CR) is to find means to use these “gaps” or “holes” in the frequency spectra and do something useful of the frequencies floating around unused and the goal of cognitive radios is to utilize under used spectrum as spectral resources are becoming sparts. We aim to develop a system model scenario and the approach is to take the decisions on the basis of power spectral density of the channel which can be used cognitively to find out the available gaps, those can be assigned to new incoming users thus improving the overall channel’s throughput & performances.

Keywords: Cognitive radio, digital communications, multiplexing, software-defined radio
