Cognitive radio and full duplex transmissions are regarded as two effective techniques to
improve the spectral efficiency. By combining the two promising techniques, the problem of …

A power allocation scheme for the secondary user when the primary user employs the full
duplex relay (FDR) is proposed in cognitive radio system. When the FDR is deployed in …

Recent developments of self-interference suppression techniques have enabled practical
implementations of full-duplex (FD) cognitive-radio (CR) communication systems. Such …

This paper investigates the power allocation between the cognitive transmitter (CT) and the
cognitive relay (CR) in a cognitive Amplify-and-Forward (AF) full-duplex relay network. To …

To solve the power supply problem of battery-limited Internet of Things devices (IoDs) and
the spectrum scarcity problem, simultaneous wireless information and power transfer …

Cognitive radio technologies are conceived as an emerging way to alleviate the current
spectrum deficit problems. However, due to the growth of low power consumption devices …

This paper investigates the energy efficiency of a full duplex (FD) cognitive radio (CR)
system in the low-power regime under a practical self-interference cancellation performance …

In this paper, we propose an anti-interference cooperative spectrum sharing strategy in
cognitive two-phase full-duplex relaying networks, in which the secondary system acts as a …

A full-duplex ultra-dense network (FDUDN) has been envisioned as a promising network
paradigm for spectrum efficiency enhancement. This paper presents a novel joint spectrum …
