An Optimal Time Reversal Waveform Based on Sequential Convex Programming for Wireless Power Transmission

Time reversal (TR) is one of the novel techniques on wireless power transmission (WPT), which can enhance transmission efficiency. In this paper, we use TR for WPT and propose a sequential convex programming for TR. We take the non-linear rectenna circuit model into consideration and carry out numerical simulations in a rich multipath environment to compare three waveforms: multi-sine, TR, TR-SCP. The results show that our approach can efficiently adapt to the complex multipath channel and the system model by achieving more output power at the receiver.
