论文摘要
在本文中,研究了基于双跳跃能量收集的固定增益扩增和前进(AF)的传播系统的性能,但会受到褪色损害的影响。我们考虑通过固定的远处继电器($ r $)与目的地节点($ d $)通信的源节点($ s $),该节点($ r $)从其接收的信号中收集能量,并使用它来扩展和将接收的信号放大到$ d $。在能量收集的分析中考虑了分解功率(PS)和时间切换(TS)方案。 $ s $ - $ r $和$ r $ - $ d $ hops分别由nakagami-$ m $和$α$ - $ - $ $ $ $ $ $ $ $ $ $ $。得出了端到端信噪比(SNR)的统计特性的封闭形式表达式,根据哪种自适应传输策略得出了四种自适应传输策略,基于哪个新型符号错误率(ASER)以及平均通道容量(ACC)的新型封闭形式表达式。派生表达式通过蒙特卡洛模拟验证。
In this paper, the performance of a dual-hop energy harvesting-based fixed-gain amplify-and-forward (AF) relaying communication system, subject to fading impairments, is investigated. We consider a source node ($S$) communicating with a destination node ($D$) through a fixed distant relay ($R$), which harvests energy from its received signals and uses it to amplify and forward the received signals to $D$. Power-splitting (PS) and time-switching (TS) schemes are considered in the analysis for energy harvesting. The $S$-$R$ and $R$-$D$ hops are modeled by the Nakagami-$m$ and $α$-$μ$ fading models, respectively. Closed-form expressions for the statistical properties of the end-to-end signal-to-noise ratio (SNR) are derived, based on which novel closed-form expressions for the average symbol error rate (ASER) as well as average channel capacity (ACC) considering four adaptive transmission policies are derived. The derived expressions are validated through Monte-Carlo simulations.
