摘要：

A novel multi-hop cooperative relaying transmission is proposed, where neither the source nor the relays have constant power supplies but rather scavenge energy from cochannel interferences (CCIs) and then use it for subsequent data transmission. The results show that, larger CCIs, usually detrimental to system performance, offer higher transmit power to each node and benefit improving system performance. Given a prescribed end-to- end (e2e) outage threshold, this letter identifies the largest number of hops that energy harvesting from CCIs can support. Moreover, the e2e outage probability is shown to be dominated by the quality of the desired channels along with the relaying link, almost regardless of the CCIs.
