碩士 === 國立交通大學 === 電信工程研究所 === 106 === In this thesis, we develop a general modeling and analytical framework for simultaneous wireless information and power transmission (SWIPT) in a heterogeneous cellular network(HetNet) and model the cell-load in order to accurately exploit the fundamental performance limits of SWIPT between base station and its user. Then, we identify a void cell phenomenon that indicates when base station has no users, which has a significant impact on the performance of SWIPT. In this thesis, we first apply a power-splitting receiver architecture to a user and analyze the statistical properties and limits of its harvested power and energy. We then model the cell load to determine how the void cell phenomenon influences the fundamental performance. Next, we derive the downlink and uplink rates that characterize the cell-load and user association effects and use these to define the energy efficiency of users. We also investigate the optimization of the energy efficiency, which helps to maximize the SWIPT performance of the receiver architecture for different user associations and network deployment scenarios. Finally, we compare the time-switching and power-splitting architectures and consider which one is better in the different situations.
