ESTIMATING DEVICE AND METHOD FOR ESTIMATING |
摘要 |
An estimating device includes a detector and an estimator. The detector detects a first parameter representing a ratio of a power of a signal component in received light to a power of a noise component in the received signal, a second parameter representing a sum of the power of the signal component and the power of the noise component, and a third parameter representing a sum of a power of a component being derived from cross phase modulation and being contained in the noise component and a power of a component being derived from spontaneously emitted light and being contained in the noise component. The estimator estimates, based on the first through the third parameters, a fourth parameter representing a ratio of the power of the signal component to a power of a component being derived from self phase modulation and being contained in the noise component. |

1. An estimating device comprising:
a detector that detects a first parameter representing a ratio of a power of a signal component in received light to a power of a noise component in the received signal, a second parameter representing a sum of the power of the signal component and the power of the noise component, and a third parameter representing a sum of a power of a component being derived from cross phase modulation and being contained in the noise component and a power of a component being derived from spontaneously emitted light and being contained in the noise component; and an estimator that estimates, based on the first through the third parameters, a fourth parameter representing a ratio of the power of the signal component to a power of a component being derived from self phase modulation and being contained in the noise component. |
