文摘

In the work, a dual-hop cooperative simultaneous wireless information and power transfer (SWIPT) system, in which there are a source–destination (S–D) pair and a relay node (R), is considered. R adopts threshold amplify-and-forward (AF)/decode-and-forward (DF) relaying schemes to decide whether to aid S–D pair’s information transmission not. The effect of SWIPT on the outage performance has been investigated and the closed-form analytical expressions for outage probability have been derived for threshold AF and DF relaying schemes, respectively, which are verified by Monte-Carlo simulations.
