Cognitive Radio and Dynamic Spectrum Sharing Systems

Call for Papers

The ever-growing need for wireless communications which provide high data rates entails a substantial demand for new spectral resources and more flexible and efficient use of existing resources. Several measurement campaigns conducted in the recent years show that frequency spectrum in the range 30 MHz–3 GHz is most of the time unused leading to low average occupancy rates and motivating to allow more flexible spectrum use. Promising solution to exploit spectrum in a flexible way is via cognitive radio and dynamic spectrum sharing systems which use innovative spectrum management and allow different systems to share the same frequency band. Significant potential improvements offered with such approaches and also positive view from regulatory bodies have led to exploding interest in this field recently. However, such paradigm shift introduces many new design challenges that have to be solved in order to enable proper functioning of the spectrum sharing and cognitive radio systems. Recent research efforts include considerations of different physical layer technologies, spectrum sensing, coexistence mechanisms between legacy and secondary users, and shared medium access among many secondary users.

The objective of this special issue is to showcase the most recent developments and research in this field, as well as to enhance its state-of-the-art. Original and tutorial articles are solicited in all aspects of cognitive radio and spectrum sharing including system and network protocol design, enabling technologies, theoretical studies, practical applications, and experimental prototypes.
