Harvesting energy from radio frequency signals is a promising solution to enhance the energy efficiency of portable wireless devices and/or wireless sensors. Toward this goal, in this thesis, wireless powered communication networks are studied. Such a network consists of a hybrid access point or a power beacon that transfers energy to the user. The user device then transmits data in the uplink by using its harvested energy. Performances of wireless powered communication networks are investigated in detail based on two practical scenarios: imperfect channel state information and nonlinear energy harvesting models. First, average throughput and average bit/symbol error rate are derived for imperfect channel state information case. Second, a new nonlinear energy harvesting model and its asymptotic version are proposed. The linear and rational energy harvesting models are also described for comparative purposes. The average throughput and average bit error rate of four energy harvesting models are investigated.
