We are in the midst of a major paradigm shift in how we manage radio spectrum. This
paradigm shift is necessitated by the growth of wireless services of all types and the demand …

The rising popularity of wireless services resulting in spectrum shortage has motivated
dynamic spectrum sharing to facilitate efficient usage of the underutilized spectrum …

In this paper, we present a novel hybrid framework combining compressive spectrum
sensing with geo-location database to find spectrum holes in a decentralized cognitive …

To underpin the predicted growth of the Internet of Things (IoT), a highly scalable, reliable
and available connectivity technology will be required. Whilst numerous technologies are …

The radio-frequency spectrum shortage, which is primarily caused by the fixed allocation
policy, is one of the main bottlenecks to the deployment of existing wireless communication …

The state-of-the-art eigenvalue-based spectrum sensing methods only consider the partial
information of eigenvalues, such as the maximum, minimum, and mean values to make …

Dynamic spectrum sharing can provide many benefits to wireless networks operators.
However, its efficiency requires sophisticated control mechanisms. The more context …

To maximize spectrum access opportunities for white space devices, incorporating real-time
spectrum sensing with geolocation database is a promising approach to enhance detection …

This paper presents an efficient method to construct white space database for devices to
communicate in TV white space (TVWS). The goal is to build a TVWS database which …

A hybrid overlay/underlay cognitive radio network (CRN) is demonstrated to provide high
spectrum efficiency and channel capacity. Decision‐making in joining CRNs is one of the …
