摘要

这种协同中继技术得到了广泛的研究，但中继传输系统的能效并不总是高于直接传输系统。本文研究了直接传输(DT)模式、单向中继传输(OWRT)模式和双向中继传输(TWRT)模式在不同信道衰落条件下的EE，得到了EE的表达式。对比三种传输方式在不同信道衰落下的EE，系统根据实际数据传输速率自适应选择EE较高的传输方式。仿真结果表明，与传统的传输方式相比，所提出的节能中继自适应传输策略大大提高了中继传输系统的能效。

High energy efficient relay adaptive transmission strategy

This Cooperative relay technology has been widely studied, but the energy efficiency (EE) of relay transmission system is not always higher than that of direct transmission system. In this paper, the EEs of the direct transmission (DT) mode, the One - way relay transmission (OWRT) mode and the two-way relay transmission (TWRT) mode in different channel fading conditions are studied, and the expressions of EE are obtained. Comparing to the EEs of the three transmission modes under different channel fading, the system adaptively selects the transmission mode with higher EE according to the actual data transmission rate. Simulation results show that, compared to the traditional transmission mode, the proposed energy-efficient relay adaptive transmission strategy greatly improves the EE of the relay transmission system.
