Energy efficiency analysis of one-way and two-way relay systems

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 consumptions (PCs) other than that consumed by transmitting information bits is taken into account, however, relaying may not be energy efficient. In this article, we study the energy efficiencies (EEs) of one-way relay transmiss...

Energy Efficiency Optimization and Comparison for One-Way and Two-Way Decode-and-Forward Relay Systems

Abstract—Energy-efficient communication techniques play great roles in applications where devices are powered by batteries. Relaying is viewed as an energy saving technique because it can reduce the transmit power by breaking one long range transmission into several short range transmissions. TwoWay Relaying Transmission (TWRT) is expected to consume less transmit power than One-Way Relaying T...

Relay Selection and Resource Allocation in One-Way and Two-Way Cognitive Relay Networks

Relay Selection and Resource Allocation in One-Way and Two-Way Cognitive Relay Networks Ahmad Mustafa Alsharoa In this work, the problem of relay selection and resource power allocation in oneway and two-way cognitive relay networks using half duplex channels with di↵erent relaying protocols is investigated. Optimization problems for both single and multiple relay selection that maximize the su...

Power Allocation Strategies in Block-Fading Two-Way Relay Networks

This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...

Performance analysis of joint relay selection and transmission schemes in multiple-antenna two-way relay systems

In this paper, we consider a two-way relay system with two multi-antenna sources and multiple single-antenna relays and study the performances for various transmission schemes with the assumption that perfect channel state information (CSI) is available at both the sources and the relays. Although a transmission scheme that combines source beamforming and relay selection (BF-RS) is known to imp...
