Abstract :
Recent advances in the smart grid for electric power supply systems require long-distance wireless power transmission with smart wireless communication technology. Whereas power transmission and information transmission have been considered separately, a few papers have been proposed a method to transmit both power and information, in which wireless power transmission beam is modulated by signals [1]. However, since the peak average power ratios for the modulated beam are larger than unity, the communication was carried out only under the sacrifice of the power transmission efficiency. Thus, to utilize the maximum capacity of transmitted power, a novel wireless technology to transmit both power and information has been eagerly demanded.
