Abstract: PURPOSE: A method and a device for transmitting and receiving coherent optical orthogonal frequency division multiplexing(OFDM) are provided to efficiently compensate phase noises although a system uses a light source with a wide line width for OFDM signals with long symbol lengths. CONSTITUTION: A transmission OFDM digital signal processing part(210) outputs in-phase digital signals and quadrature digital signals. A digital to analog converter(220) converts the in-phase digital signals and the quadrature digital signals into analog signals.

An optical in-phase/quadrature modulator(240) outputs coherent optical OFDM signals containing the additional pilot tone signals by upwardly converting the analog signals based on additional pilot tone signal added in-phase components and quadrature components.
