A scheme for combining data rate, energy efficiency and relay location in bidirectional amplify-and-forward relay networks is proposed in this paper. The proposed scheme allows the energy consumption to be evaluated for all positions of a chosen relay along a line between the transmitter and the destination. Furthermore, the evaluated energy reduction is used to obtain the optimal balance between...
This paper presents a new method combines Optimal Relay Location (ORL), Energy Efficiency (EE) and Spectrum Efficiency (SE) in a bidirectional relay networks. The proposal aims to minimize power consumption with lower data rate loss. For this work, a flat fading channel is considered for exchanging signals between two wireless users separated by a specified distance. This distance is splitted by a...
A new method for analyzing the Asymptotic Bit Error Rate (ABER) performance of a two way Amplify-and-Forward Multiple Relay (TAF-MR) network is proposed in this paper. In this network a relay selection scheme is adopted to choose a single relay, which has the highest Signal-to-Noise-Ratio (SNR). The selected relay forwards the signal from the source to the destination through flat-fading channels...
