What is spectrum sharing in cognitive radio networks?
Spectrum sharing is a promising technique to enhance spectrum utilization in cognitive radio environments. Cognitive sharing the spectra of licensed users provides unlicensed users with the opportunity to access rigid spectrum resources without degrading the performance of the licensed users.
What are the techniques used in spectrum sharing?
The spectrum sharing techniques can be classified as: interweave, underlay, and overlay [6]. In interweave spectrum sharing; the secondary system can dynamically access the spectrum holes. For spectrum underlay, secondary users (SUs) are simultaneously transmitting with the primary users (PUs).
What is spectrum sharing?
Spectrum sharing is the logical partitioning of optical spectrum on a submarine cable for different end-users, such that each end-user has its own ‘virtual fiber pair. ‘ Virtualization has revolutionized IT operations in companies around the world.

What is cooperative spectrum sensing?
Cooperative sensing is a solution to enhance the detection performance, in which secondary users collaborate with each other to sense the spectrum to find the spectrum holes. Learn more in: Interference Statistics and Capacity-Outage Analysis in Cognitive Radio Networks.
What is the meaning of cognitive radio network?
Cognitive radio (CR) is a form of wireless communication in which a transceiver can intelligently detect which communication channels are in use and which are not. It instantly moves into vacant channels while avoiding occupied ones.
What is spectrum sharing in 5G?
What is Dynamic Spectrum Sharing? Dynamic Spectrum Sharing (DSS for short) is a new antenna technology that for the first time enables the parallel use of LTE and 5G in the same frequency band. The technology determines the demand for 5G and LTE in real-time.
What is Ericsson spectrum sharing?
Ericsson Spectrum Sharing enables service providers to launch 5G quickly within existing 4G bands. When sharing spectrum, measuring the radio channel conditions and allocating the use of radio resources, in real-time, is vital.
What is DSS in network?
Dynamic Spectrum Sharing (DSS for short) is a new antenna technology that for the first time enables the parallel use of LTE and 5G in the same frequency band. The technology determines the demand for 5G and LTE in real-time.
What is meant by spectrum sensing?
Spectrum sensing is the process of periodically monitoring a specific frequency band, aiming to identify presence or absence of primary users.
Why is cognitive radio used?
Cognitive radio (CR) is a form of wireless communication in which a transceiver can intelligently detect which communication channels are in use and which are not. It instantly moves into vacant channels while avoiding occupied ones. It does not cause any interference to the licensed user.
