Abstract (in Japanese) (See Japanese page) 
(in English) We have proposed the novel method for secure security in a satellite communication. A third person can not to demodulate and reproduce data when receives QPSK modulation signal. Because the signal giving the phase rotation angles that is only known by the authorized a transmitting station side and a receiving station side. It's difficult to be intercepted, it's also expected for satellite communication services as well as satellite control system in a secure purpose satellite communication. So we tried this system using 16QAM modulation for increase the transmission capacity. In this paper, we design a circuit and describe the result on which we experimented actually.
