In an indoor environment rich in scatterers, wideband signals sent by a transmitter create multiple resolvable transmission paths towards a low-power receiver. Therefore, spatial gains can be exploited for increasing the performance of wireless information and energy provision without implementing multiple antennas. The transmit signal shaping vector at the transmitter and the power splitting ratio at the receiver is jointly optimised for maximising the attainable information throughput, while satisfying the receiver’s requirement on the harvested direct current (DC). The numerical results demonstrate the advantage of our design over a time-reversal counterpart and a uniform counterpart.
