摘要：

In this<?show [AQ ID=Q1]?> study, the performance of downlink simultaneous wireless information and power transfer (SWIPT) networks over Nakagami-m fading is analysed. The SWIPT network is modelled as a two-tier heterogeneous network, where one tier is the information transmission network and the other is the power transmission network. The seamless integration enables both data and energy to be transferred from access points to the users. Using the stochastic geometry theory, the expressions for outage probability at the information receiver are derived in decoupled and integrated SWIPT networks. Also, the average harvested energy at the power receiver is derived assuming a non-linear energy harvesting model. Simulation results validate the analytical expressions and the impacts of various system parameters on the SWITP performance are investigated.
