摘要：

This paper analytically investigates the performance of a wireless powered communication system, where a wireless sensor powered by multiple dedicated power beacons (PBs) communicates with a destination. Specifically, we consider a harvest-then-transmit multiple-input and multiple-output (MIMO) communication system, where the locations of the PBs and the interferers are characterized by stochastic geometry tools. In the considered network, both the energy transfer and the information transmission are achieved by adopting MIMO beamforming, and the effect of co-channel interference is taken into account. Under this architecture, we analytically derive the expected energy harvesting rate and an upper bound of the expected transmission rate. Numerical results have shown the impacts of the antenna number, the density of PB and the transmit power of PB on the expected energy harvesting rate and the expected transmission rate.
