As the demand for higher data rate is exponentially growing, spectral efficiency improving
methods can be adopted in recent day's wireless communication systems. If the cognitive …

This paper studies energy efficiency (EE) and average throughput maximization for cognitive
radio systems in the presence of unslotted primary users. It is assumed that primary user …

This paper delivers an accurate approximation for adaptive threshold and optimal frame
detection algorithms based on the robust multi-taper method aiming at an efficient spectrum …

As a key technology to discover idle spectrum in cognitive radio (CR) networks, classical
spectrum sensing schemes mainly focus on the improvement of sensing accuracy and …

In this paper, we propose a cognitive radio timing protocol (CRTP) to optimize the time
allocation for different phases of cognitive radio (CR) operation to maximize the throughput …

Under the conventional approach of spectrum sensing in a cognitive radio (CR) system, in
the start of each frame of duration TT a time slot τ τ is allocated for the spectrum sensing and …

Green wireless communication has drawn ample interest in the 5G cellular networks. In this
article, we investigate an energy‐efficient power allocation with spectrum sensing for …

This paper presents extensive experimental characterization and empirical modelling of
802.11 temporal behavior. A detailed characterization of 802.11 b/g/n homogeneous and …

The game theory framework in cognitive radio (CR) networks enables the secondary users
(SUs) to identify and assign channels left unused by the primary users. The SUs in the …
