Outage Analysis and Power Allocation Optimization for Multiple Energy-Harvesting Relay System Using SWIPT

Algorithm 1

The optimal power splitting factor design under each relay’s power constraint.

(1)	Using the transmit power and the energy conversion efficiency in problem (37) to obtain power splitting factor for each relay.
(2)	Using in to obtain each relay’s transmit power .
(3)	if ,
(4)	;
(5)	else
(6)	end
(7)	Using to achieve the final outage probability.
