摘要

本文研究了基于译码转发(DF)的同步无线信息与电力传输(SWIPT)系统的性能，并用中断概率和遍历容量来评价该系统的性能。在SWIPT系统中，源节点通过能量受限的DF中继节点将信号传输到目的节点。为了利用源节点到目的节点的直接链路，目的节点采用选择组合(SC)方案将来自不同链路的信号进行合并。导出了系统停机概率和遍历容量的封闭形式和积分结果。仿真结果表明，该方案的性能优于现有方案。

Performance Analysis of Decode-and-Forward Based SWIPT Systems with Direct Link

The performances are investigated in the paper for the decode-and-forward (DF) based simultaneous wireless information and power transfer (SWIPT) system, which are evaluated by the outage probability and ergodic capacity. In the SWIPT system, the source node transmits the signal to the destination node via an energy constrained DF relay node. For utilizing the direct link from the source node to destination node, the destination node adopts the selection combining (SC) scheme to merge the signals coming from different links. The closed-form and integral results for the outage probability and the ergodic capacity of the system are derived, respectively. Simulation results show that the performance of the proposed DF SC scheme is superior to the existing schemes.
