摘要

提出了一种结合双向中继网络中最优中继定位(ORL)、能量效率(EE)和频谱效率(SE)的新方法。该方案的目标是在降低数据速率损失的同时最小化功耗。在这项工作中，考虑了一个平坦衰落信道，用于在相隔一定距离的两个无线用户之间交换信号。该距离由一组双向放大和转发(AF)中继节点分割，该节点允许放大输入信号而无需任何进一步处理。首先对这些继电器的位置进行优化，然后推导出EE和SE之间的权衡表达式。所有解析表达式(即最优继电器位置和权衡EE SE)都通过仿真得到证实。

Energy Efficiency and Spectrum Efficiency trade-off over Optimal Relay Location in bidirectional relay networks

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 set of bidirectional Amplify-and-Forward (AF) relay nodes that allow to amplify the input signal without any further processing. The locations of these relays are optimized first and the trade-off expression between EE and SE is then derived. All analytical expressions (i.e., optimal relay location and trade-off EE SE ) are corroborated by the simulation.
