Abstract: PURPOSE: A tap update control device is provided to improve noise level estimation performance by restricting the number of tap update times using simple structure. CONSTITUTION: A feed forward filter(100) filters inputted signal. The feed forward filter outputs the filtered signal to a first adder(120). A feedback filter filters the signal outputted from a decision unit(130). The feedback filter outputs the filtered signal to the first adder. The first adder adds the inputted signals. The decision unit determines the symbol based on the inputted signals.

Abstract: A performance monitor of the optical signal and a method thereof restoring the optical signal according to the performance of the optical signal are provided to improve the reliability of optical network and monitor the performance of the degraded optical signal at each node. A signal extraction part(100) extracts the signal of the specific wave among the inputted optical signal. A photo-electro transform part(110) converts the optical signal of the specific wave extracted from the signal extraction part into the electric signal. An overhead interpreter(120) determines the performance degradation of signal. According to the interpretation result of the extracted overhead, the controller(130) monitors the performance of the optical signal.
