<p>PROBLEM TO BE SOLVED: To solve such a problem that when transmitting a plurality of signals with the same frequency, while mixing, the mixed signals cannot be separated if the signal strength is equivalent.SOLUTION: A signal separation device includes a delay unit for outputting the other mixed signal, out of one and the other mixed signals of a plurality of mixed signals including the signals from a plurality of transmission stations, while delaying, a multiplier for outputting the one mixed signal and the output from the delay unit while multiplying, an integrator for outputting the output from the multiplier while integrating, and a peak detector for detecting the peak of output from the integrator, and outputting the delay time when a peak occurs. The peak detector outputs a correction time that is used for taking out the one and the other signal, respectively, from the transmission station.</p> |
