Original Abstract Submitted

an ifof scheme optical transmission system according to the present disclosure includes a transmission-side digital signal processing device including a correction processing unit and a calibration signal generating unit, and a reception-side digital signal processing device including a digital separation processing unit and a weight correction value calculating unit, in which the calibration signal generating unit generates a calibration signal (s(t)), the digital separation processing unit performs demultiplexer processing to separate the calibration signal (s(t)) into a plurality of baseband signals (s(t), s(t), . . . , s(t)), the weight correction value calculating unit calculates parameter coefficients (a, a, . . . , a) on the basis of the baseband signals (s(t), s(t), . . . , s(t)), and the correction processing unit corrects an amplitude of each of a plurality of input radio signal strings that is input using the parameter coefficient (a, a, . . . , a).
