In this work, we investigate the benefits of secondary user (SU) network beamforming on
improving primary user (PU) location privacy in spectrum sharing systems, where the …

In dynamic spectrum sharing (DSS) ecosystem with non-informing incumbent users (IUs),
Environmental Sensing Capability (ESC) system has been proposed to detect IU activity …

In dynamic spectrum access (DSA), secondary users (SU) should only be allowed to access
a licensed band belonging to incumbent users (IU) when the quality-of-service (QoS) …

Database driven dynamic spectrum sharing is one of the most promising dynamic spectrum
access (DSA) solution to address the spectrum scarcity issue. In such a database-driven …

In dynamic spectrum access, commercially operated database servers are often used to
assist opportunistic users (OUs) to query and access spectrum vacancies of incumbent …

Dynamic spectrum sharing has emerged as a promising solution to address the spectrum
scarcity challenge. Currently, the FCC has designated several Spectrum Access Systems …

In dynamic spectrum access (DSA), Environmental Sensing Capability (ESC) systems are
implemented to detect the incumbent users'(IU) activities for protecting them from secondary …

In dynamic spectrum access, commercially-operated database servers are often used to

Cognitive radio is emerging as a technology to alleviate spectrum shortage and to improve
spectrum utilization. In database-driven cognitive radio networks (CRNs), secondary users …

Dynamic spectrum access enables opportunistic users (OUs) to access underutilized
licensed bands by querying spectrum databases. However, the operational details of the …
