Dynamic spectrum sharing (DSS), in which multiple wireless systems share the same radio resource, has been considered to improve frequency utilization efficiency. In DSS, the observer measures the channel occupancy rate (COR) and the number of radio

Spectrum Sensing Scheme Measuring Packet Lengths of Interfering Systems for Dynamic Spectrum Sharing
Publikováno v:
IEEE Access, Vol 9, Pp 135160-135166 (2021)
For the dynamic spectrum sharing (DSS), this paper proposes a spectrum sensing scheme that measures packet lengths of interfering systems. DSS requires spectrum sensing techniques to measure a length of time for which the interfering systems use a ch

In dynamic spectrum access based on cognitive radio, two terminals (master and slave) cannot recognize the accessing channel. For exchanging the control signal in order to recognize the accessing channel, the rendezvous channel scheme based on channe

A rendezvous scheme based on frequency hopping can compensate for this mismatch by exchanging control signals through a selected channel in accordance with a certain rule. However, conventional frequency hopping schemes have not considered an access

This paper proposes the novel high accuracy and low complexity measurement for channel occupancy ratio (COR) and channel transition ratio (CTR). In cognitive radio, the terminal selects the suitable channel in order to obtain more access opportunitie
