摘要

本文研究了具有译码转发(DF)和放大转发(AF)中继协议的全双工(FD)两跳中继系统的能量效率(EE)。首先将剩余自干扰(RSI)建模为中继发射功率的线性函数。然后，在传输速率不变的情况下，将EE最大化问题转化为发射功率最小化问题，得到DF和AF协议的最小发射功耗。在最小传输功耗条件下，给出了DF协议和AF协议的EE比较。仿真结果验证了理论分析和比较。

Energy Efficiency Comparison for Full-Duplex DF and AF Relaying Protocols

In this paper, the energy efficiency (EE) of full-duplex (FD) two-hop relay system with decode-and-forward (DF) and amplify-and-forward (AF) relaying protocols is studied. The residual self-interference (RSI) is modeled as a linear function of relay transmit power first. Then, with the constant transmission rate, the EE maximization problem is transformed into transmit power minimization problem and the minimum transmit power consumptions of the DF and AF protocols are obtained. Furthermore, the EE comparison of the DF and AF protocols is given with the minimum transmit power consumption. The simulation results are given to verify the theoretical EE analysis and comparison.
