Abstract (in Japanese) (See Japanese page) 
(in English) In distributed cooperative microwave WPT, it is important to synchronize the frequencies of multiple transmitters in order to maximize the received power to the receivers. In conventional transmitters, the multiple transmitters supplied local signal distributed from 920 MHz source, but there are problems with the size of the transmitter and insertion loss due to cable length. In this research, instead of sharing the 920 MHz signal, each transmitter generates a 920 MHz signal from 10 MHz reference signals, thereby solving the problems of transmitter, and propagation loss, and achieving frequency synchronization. By implementing signal processing using GNU Radio to control multiple transmitters, we constructed a transmitter control system and conducted a power transmit experiment in an anechoic chamber.
