| Summary: | 碩士 === 國立中央大學 === 通訊工程學系 === 104 === Due to the unpredictability of conventional energy harvesting and the shortage of radio spectrum resource, wireless power transfer (WPT) and device-to-device (D2D) communication have emerge as promising areas. The existing research of simultaneous wireless information and power transfer (SWIPT) only focus on the downlink scenario of cellular network where the devices can harvest the power from the transmitted signal and some studies with D2D are only pay attention to reuse the uplink channel. Based on the scenario from above references, base-station (BS) can transmit more power to charge the D2Ds and has more ability to against the D2Ds interference, and compared to the downlink channel, reuse the uplink channel which is less congested is a better choice, also D2D users can monitor the received power of downlink control signals and only estimate the path-loss between D2D transmitter and the BS. In this thesis, we focus on cellular networks with multiple antennas deployed underlying wireless-powered D2D which harvest power from downlink and transmit on uplink and optimize D2D sum throughput.
