Local oscillator frequency offset compensation in a coherent optical signal receiver |
摘要 |
A system and method implementing dual stage carrier frequency offset compensation (FOC) in a coherent receiver for an optical communication system. In the first stage, a feed forward FOC function compensates for relatively slowly drifting frequency offsets. In a second stage, a decision-feedback FOC function compensates for relatively quickly drifting frequency offsets. The feed forward frequency offset compensation may be implemented with a feed forward carrier phase estimation function and the decision-feedback frequency offset compensation may be implemented with a decision-feedback carrier phase estimation function. |
