<P>PROBLEM TO BE SOLVED: To automatically and accurately identify a modulation system, even when there are distortions in the arrival reception signal. <P>SOLUTION: Signal modulation system identification systems 1 and 1A comprise an ideal waveform system 2 for measuring an identification parameter by adding distortions to the ideal signal waveform; an actual signal system 3 for measuring the identification parameter, by collecting actual digital modulation signals; identification object signal systems 4 and 4A for receiving the digital signals to be identified, and for identifying a modulation system by measuring/comparing the identification parameters of the digital signals; and a database 5 for supplying the identification parameters. <P>COPYRIGHT: (C)2008,JPO&INPIT |
