摘要：
This paper considers a dual-hop wireless powered cooperative system with multiple relays, which consists of a source (S), a destination (D), and multiple relay candidates. These relay candidates can harvest energy from the interference signals to transfer the decoded data to D. Two classic relay selection schemes, i.e., the optimal source-relay link (OSRL) and optimal source-relay-destination link (OSRDL) schemes, are considered to choose a best relay to aid the transmission between S and D under the conditional decode-and-forward (DF) scheme. The closed-form expressions of the outage probability for the two considered relay selection schemes have been derived and verified over independent Nakagami-m fading channels.
