Signal processing for cooperative cognitive radio networks by Rabiee, Ramtin

“…In recent decades, cognitive radio has been introduced as a practical solution to solve the frequency scarcity problem by setting up a secondary network besides the primary one through a cognitive radio network (CRN) to increase the utilization rate of licensed frequency bands. There exist many parameters to achieve a reliable and practical CRN and it is necessary to conduct extensive signal processing studies to optimize them. …”
