Optimal Frequency-Spreaded Signal Forming for Wireless Power Transfer

The paper is devoted to forming a power-carrying signal for RF wireless power transfer. The approach takes into account the limitation on power level at a particular frequency. The research presents an algorithm for the signal to be transferred to match the propagation channel. The approach is based on experimental estimates of the wireless channel and the formation of the appropriate signal based on the measurement results. The paper gives the theoretical substantiation of the method and shows its application to wireless power transfer.
