Relaying is supposed to be a low energy consumption technique since the long distance
transmission is divided into several short distance transmissions. When the power …

In this paper, we study energy efficient orthogonal frequency division multiplexing (OFDM)
relay system, where two source nodes communicate with each other via a half-duplex …

This paper proposes a new method of maximising the energy efficiency of Aerial Robotic
(AR) networks in order to prolong AR battery life. An AR network is composed of an …

In this letter, we study a classic three-node relay network with two end nodes and one relay.
A unified signal model is proposed to represent four typical relay modes, namely, one-way …

Spectrum sharing between primary and secondary systems is discussed in this paper. A two-
phase spectrum sharing protocol is proposed by using analog network coding (ANC), in …

Recently, the energy efficiency of a relay network has become a hot research topic in the
wireless communication society. In this paper, we investigate the energy efficiency of three …

This paper investigates the outage probability and ergodic capacity performances for full‐
duplex mode in two‐way amplify‐and‐forward relay channels. The two‐way relay channels …

Channel estimation error results in severe performance deterioration in wireless networks. In
this paper, we study the impact of imperfect channel estimation (ICE) on the outage …

In this paper, we consider a two-way cognitive cooperative radio network (TW-CCRN) with
hybrid interweave-underlay spectrum access in the presence of imperfect spectrum sensing …

Two-way relaying is more spectral efficient than one-way relaying and is expected to
consume less transmit power than one-way relaying to achieve the same data rate …
