Принципи роботи мереж когнітивного радіо

Abstract

The cognitive radio system can be organized using a database containing information about the surrounding radio space (for example, about radio access technologies) and using a control channel. Current research focuses on the concept of using the control channel, in particular the project of the European consortium of the largest telecom operators E2R. The point is that the delivery of the necessary information is carried out through a kind of common control channel, which allows the terminal to know about the employment status of the radio channel. The paper considers the method of using the control channel for the functioning of cognitive radio.
