TRANSFER FUNCTION ESTIMATION DEVICE, TRANSFER FUNCTION ESTIMATION METHOD AND PROGRAM

原文（中国語）

A transfer function estimation device includes a composite transfer function calculation unit that calculates a composite transfer function which is obtained by combining a transmission transfer function that affects a signal transmitted by an optical transmitter and a reception transfer function that affects a signal received by an optical receiver in each of frequency offsets that are differences between a frequency of a carrier wave input to an optical modulation unit in the optical transmitter and a frequency of a carrier wave input to an optical demodulation unit in the optical receiver based on a signal transmitted by the optical transmitter and a signal received by the optical receiver, and a transfer function separation unit that calculates the transmission transfer function and the reception transfer function from the composite transfer function based on dependency of the composite transfer function on the frequency offset.
