摘要

The double-relay cooperative user transmission network with energy harvesting is investigated and time switching-based double-relay cooperative transmission (TSDRCT) protocol is designed in this paper. In such a system, a source node transmits information to its destination node with the help of two energy harvesting cooperative nodes. The system outage probability is analyzed and an explicit expression for the outage probability is derived for decode-and-forward (DF) relay protocols, then simulation experiments are provided. The simulation results demonstrate the accuracy of the theoretical analysis, and also show that the proposed TSDRCT with energy harvesting relay is much better than traditional non-cooperative scheme in term of outage performance, and it does not increase system energy consumption.
