摘要
Embodiments of the present disclosure disclose a coherent receiver, including: a frequency offset estimation unit and a frequency offset compensation unit, where the frequency offset estimation unit is configured to receive signal light and local oscillator light, where the signal light is received by a first photoelectric detector, and a first intensity value is obtained, the signal light is received by a second photoelectric detector, and a second intensity value is obtained, the local oscillator light is received by a third photoelectric detector, and a third intensity value is obtained, and the local oscillator light is received by a fourth photoelectric detector, and a fourth intensity value is obtained; and the frequency offset compensation unit is configured to obtain a frequency offset value between the signal light and the local oscillator light according to a difference between a first ratio and a second ratio.
