Low-power, high-linearity transconductor with a high tolerance for process and temperature variations
A novel scheme for tunable complementary metal–oxide–semiconductor (CMOS) transconductor robust against process and temperature (PT) variations is presented. The proposed configuration is a voltage controlled circuit based ...
Robust Statistics Evidence Based Secure Cooperative Spectrum Sensing for Cognitive Radio Networks
Cognitive radio networks (CRNs), an assemble of smart schemes intended for permitting secondary users (SUs) to opportunistically access spectral bands vacant by primary user (PU), has been deliberated as a solution to ...
Energy Efficient Relay Selection Algorithm for Virtual MIMO Cooperative Networks
In this paper, we propose a distance based energy efficient multiple relay selection algorithm for cooperative virtual Multiple-Input-Multiple-Output (MIMO). The fundamentals of this method is to forward the source signal ...
Jointly optimized echo state network for short-term channel state information prediction of fading channel
Accurately obtaining channel state information (CSI) in wireless systems is significant but challenging. This paper focuses the technique of machine-learning-based channel estimation. In particular, a jointly optimized ...
Efficient Evidence-based Decision Fusion Scheme for Cooperative Spectrum Sensing in Cognitive Radio Networks
In this article, an evidence based decision fusion cooperative spectrum sensing (CSS) schemes has been considered for overcoming the hidden terminal problem, improving reliability, and increasing SU agility. Under practical ...
A Stochastic based Physical Layer Security in Cognitive Radio Networks: Cognitive Relay to Fusion Center
Cognitive radio networks (CRNs) are found to be, without difficulty wide-open to external malicious threats. Secure communication is an important prerequisite for forthcoming fifth-generation (5G) systems, and CRs are not ...
