A Survey of Dynamic Spectrum Access
IEEE Signal Processing Magazine, 2007Compounding the confusion is the use of the broad term cognitive radio as a synonym for dynamic spectrum access. As an initial attempt at unifying the terminology, the taxonomy of dynamic spectrum access is provided. In this article, an overview of challenges and recent developments in both technological and regulatory aspects of opportunistic spectrum

Advanced Dynamic Channel Access Strategy in Spectrum Sharing 5G Systems
IEEE Wireless Communications, 2017 5G wireless communications aim at providing higher data rates, spectral efficiency, and energy efficiency than 4G. To achieve this target, the spectrum resource with low utilization is emptied out for 5G refarming.

Asynchronous Dynamic Spectrum Access
IEEE Transactions on Vehicular Technology, 2012Synchronization among primary users (PUs) and secondary users (SUs) is either explicitly or implicitly assumed in the literature to allow reliable dynamic spectrum access (DSA) and cognitive radio (CR) networking. However, in realistic DSA that supports ad-hoc transmissions, perfect synchronization is not attainable in the absence of a centralized ...

Dynamic spectrum access as a service
2012 Proceedings IEEE INFOCOM, 2012Recently there have been various studies on dynamic spectrum access (DSA) approaches, e.g., opportunistic spectrum access and spectrum auction, to address spectrum scarcity and inefficient spectrum utilization caused by today's static spectrum allocation policy.

On the usefulness of spectrum prediction for dynamic spectrum access
2016 8th International Conference on Wireless Communications & Signal Processing (WCSP), 2016Spectrum prediction, as one enabling technique for dynamic spectrum access (DSA), has recently been received ever-increasing research attention. Most related studies (explicitly or implicitly) assume that spectrum prediction is useful for DSA. However, it does't fundamentally clear when spectrum prediction is really beneficial.
