The DF-AF Selection Relay Transmission Based on Energy Harvesting

Aiming at the energy consumption of relay system, we propose that applying energy harvesting to cooperative communication, combing energy harvesting with DF-AF selective relay, and propose a DF-AF selection relay transmission based on energy harvesting model. This paper analyzes the system's outage probability and deduces the closed-form expression of the system's outage probability. Under the condition that the collected energy of relay is uncertain, the relay allocates energy between different time slots. Due to the energy coupling between the slots, a decoupling method is proposed, which makes the energy allocation based on the outage probability simple and feasible. The simulation results prove the feasibility of our system model and analyze the influence of the change of parameters on the probability of outage.
