Performance of Joint Interference and Data Buffer Management for Cognitive Radio
MetadataShow full item record
Cognitive Radio is a technology where Software Defined Radio functionality is augmented in order to permit a radio system where its operations will be adjusted depending on the environment. This capability offers a variety of benefits, first of all to solve the problem of spectrum scarcity.This Master's thesis proposes a solution based on sensing interference and data queue back-pressure. For this purpose, a Matlab simulator has been done to simulate some scenarios and prove the theory in a practical way. The thesis has shown how sensors can be used to listen to the mutual interference between Primary System and a Secondary System. The results show how sensors are important for two such different systems to be working at the same time in the same frequency.
