However, the beamforming system typically requires the receiver to return the channel state information (CSI) between the receiver and the transmitter. Beamforming performance is degraded by imperfect channel state information known to the transmitter. Although the more accurate channel state information can provide better beamforming benefits, but the energy and time required for CSI feedback can’t be infinitely increased to achieve perfect since the receiver's energy and feedback time of the CSI are limited. We consider a point-to-point MISO communication system. At the downlink time, the receiver will be the way the power splitter for simultaneous information and energy transfer, and feedback channel state information at the uplink time. The first part of the paper explores the situation that the receiver can directly use the energy obtained in the current time to feedback the channel state information. To maximize the downlink information throughput, the suboptimal solution of the power splitter parameter and downlink time allocation is found by simplifying the optimization problem. The second part is to add an energy storage device to the receiver. The power splitter parameters and the downlink time allocation are determined by the receiver depending on the channel state and the state of the energy storage device. Then, we use Markov decision process (MDP) according to the past observation and the current state to find the best transmission policy. Meng-Lin Ku 古孟霖 2017 學位論文 ; thesis 57 zh-TW |
