Time‐switched energy harvesting amplify‐forward relay with direct link: Performance analysis.

Summary: A dual‐hop time‐switched (TS) energy harvesting (EH) amplify forward (AF) relay system has been considered, which comprises three nodes: source (S), destination (D), and an energy harvesting relay (R), respectively. Besides the relay link, the proposed architecture has an additional direct link between the source and destination node. For this model, we derive the expressions for system outage probability and throughput. The proposed architecture shows significant performance increments in terms of system outage probability and throughput when compared with a traditional EH relay system having no direct link.
