Turbulent Two-Dimensional Shear Flows,users are categorized based on applications running on their devices. They could be either delay-tolerant or real-time applications which are approximated by logarithmic utility functions and sigmoidal-like utility functions, respectively. The objective is to share spectrum resources from multiple b

Specifically, they can operate in a totally blind manner while they offer remarkably improved performance for specific types of signals, especially when compared to energy-based methods. Until recently, most of the cooperative EBSS techniques that could be found in the litera

https://doi.org/10.1007/978-1-4615-8738-5), it conciliates the existing conflict between the ever-increasing spectrum demand and the currently inefficient spectrum utilization. The basic idea of DSA is to provide proper solutions that allow sharing radio spectrum among several radio communication systems and optimize the overall spectrum u
